If an error occurs while loading a module or one of the tests,
multiple.test will exit leaving the working modules loaded. This leaves
the system in an unwanted state and causes the test that previously pass
to fail (succeeding before being loaded for multiple.test's point of
view).
Cleanup the loaded modules before exiting due to errors.
Also take this opportunity to factorize the test for the different
distros.

This test is no longer needed. I had previously converted it to a unit
test and forgot to remove its integration test counterpart.

Hardcode a blacklist of modules in multiple.test so we can deal
with conflicts while only updating the test when those arise.

Dynamically compile module list based on -LOADED.test files in all
multiple.test scripts.
The scripts is now the same across all three directories so it might be
good to deduplicate it somehow along with other common tests.

Cleaning house a bit. Now that we have unit tests, a lot of these tests
aren't very useful anymore.

After doing some research, I've discovered that most of these tests no
longer test what they were originally intended to test.
An exception here is the 'macro-hooks' test, which is probably better
suited as an integration test, so I removed its unit test and kept its
integration test.
Really, most of these tests weren't all that useful to begin with, so
it's not a big loss. The one exception is 'gcc-static-local-var-2',
which was originally meant to test multiple static local variables with
the same name in the name function. That's a good thing, so I'll try to
come up with another test for that which works with Linux 4.16.

The test case gcc-static-local-var-2 doesn't uses any macros
from kpatch-macros.h, so remove the hunk including it.

This patch adds a reproducer testcase for correlating static local
variables added in .rodata* section, ahead of .toc section. This
testcase is for issue seen on PowerPC. For more details on the issue
refer pull request: 793.
It add's the testcase for:
- Fedora-27 Kernel version 4.15.10-300
- Centos-7 Kernel version 3.10.0-693 and
- Ubuntu-16.04 Kernel version 4.13.0-25.29

Upstream 4.15 kernels provide support for pre and post (un)patch
callbacks, inspired by the kpatch load hooks. Add support for them
in the livepatch-patch-hook.
At the same time, convert the kpatch hooks to use the same API.
