btrfs-progs: tests: speed up fsck/037 free space tree test

Browse Source 
The runtime of the test is over 4 minutes when hosted on NFS, the
fallocate phase takes the most time. As fallocate can't take multiple
arguments, we can't save the overhead by creating the files at once.

Create the files in batches in the background, this improves the runtime
to 2 minutes.
