Using upstream as a target to compile xfsprogs code, following
failure is encountered:

Command 'make' failed.\nstdout: b"libtoolize -c -i -f\nlibtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, '.'.\nlibtoolize: copying file './config.guess'\nlibtoolize: copying file './config.sub'\nlibtoolize: copying file './install-sh'\nlibtoolize: ... (5.46 s)

Add inih-devel package as dependency so that this package will be
installed.

With upstream as a target, xfstest test fails to copy local.config

(1/1) fs/xfstests.py:Xfstests.test;run-disk_type-fs_type-fs_xfs_4k-run_type-upstream-8eea: ERROR: stat: path should be string, bytes, os.PathLike or integer, not NoneType (23.60 s)

This happens since teststmpdir directory is changed during compilation
of upstream code (various progs).

Move the stub before the upstream as a target check stanza to avoid
this failure.

In case a certain package install operation fails, the test fails
with a completely different message

ERROR: 'Xfstests' object has no attribute 'scratch_mnt' (15.37 s)

The package install function is called before various variable
initialization. In case of install fail, test errors out due
to usage of uniniitalized variables in teardown.

Move the package install function call post variable initialization

On SUSE some of the packages used by xfstest script are available
with a different name.

Update the __setUp_packages function accordingly to use the correct
package names.
