Fix the following issues in the test suite:
- lack of quoting for variables
- declare function variables local when missing (prevent accidental
overwrite of global variables)
- for variables with underscore in the name use plain "$VAR_NAME"
instead of { } (unless necessary)
- minor style adjustments like moving quotes to the end of the same
string

Since a few days the CI started to fail randomly when there were loop
devices used in the tests. The mount fails because some device is
reported to be missing:
$ losetup --show --find
/dev/loop3
...
$ mkfs ...
ERROR: device scan failed on '/dev/loop3': No such file or directory
...
$ mount
mount: /home/runner/work/btrfs-progs/btrfs-progs/tests/mnt: wrong fs
type, bad option, bad superblock on /dev/loop3, missing codepage or
helper program, or other error.
$ dmesg
...
BTRFS error (device loop0): devid 3 uuid 11d9c345-9527-433e-a024-7102659fa0ee is missing
BTRFS error (device loop0): failed to read the system array: -2
BTRFS error (device loop0): open_ctree failed
This was reproducible in the "cli" tests, but also happened on a local
machine.
To fix that wait for all loop devices before mount, the command
'btrfs device ready' should block until that. The convenience helper
does that, for any standalone 'mount' used with loop devices this must
be done manually.

[PROBLEM]
Since we have migrated to default v2 cache, the test case
misc/030-missing-device-image is no longer executed:
[TEST/misc] 030-missing-device-image
[NOTRUN] unable to create v1 space cache
[CAUSE]
The test case itself is trying its best to cover all paths, including
the data extent read path.
Thus the test case is requiring v1 cache, as that's the only way to
cover the data read path.
[FIX]
Just remove the v1 space cache requirement, it's still better to run the
test even it only exercises the metadata read path.
The good news is, after commit 3ff9d35257 ("btrfs-progs: use
read_data_from_disk() to replace read_extent_from_disk() and replace
read_extent_data()"), all data/metadata read paths are unified.
They only difference is the verification part.
Thus even if we didn't fully exercise the data read path, we didn't lose
much coverage anyway.

Executing the script inside the directories as './test.sh' is not
supposed to work but could happen accidentally. With an exit after
attempting to source the we can fix that.
