[PATCH 2/2] fsx: add missing fallocate flag ifdefs

[Brian Foster <bfoster@redhat.com>]

The various fallocate flags are mostly ifdef'd for backward
compatibility with the exception of the associated test_fallocate()
calls to verify functionality at runtime. I suspect the reason for
this was to avoid ifdef ugliness around having to clear the runtime
flag for each operation, but unfortunately this defeats the purpose
of the ifdef protection everywhere else.

Factor out the fallocate related test calls into a new helper and
add the appropriate ifdefs.
