[LTP] [PATCH v7 3/7] lib: Add script for running tests

[Petr Vorel <pvorel@suse.cz>]

For now run only tests which TPASS or TCONF.

tst_fuzzy_sync01: sporadically fails, thus disabled:

../../include/tst_fuzzy_sync.h:685: TINFO: Exceeded execution loops, requesting exit
tst_fuzzy_sync01.c:227: TFAIL: acs:3  act:1  art:1  | =:23   -:46   +:2999931
...
Summary:
passed   21
failed   3

Redirect stderr to stdout to workaround mangled output on GitHub Actions
where stdout and stderr are probably block buffered and flushed at
different times.

NOTE: test_zero_hugepage.sh is testing C API, thus added in
LTP_C_API_TESTS. Using shell tests also in C API tests i.e.
test_zero_hugepage.sh (helpers to setup environment tests) requires
to search file also in src directory (required for out-of-tree builds).

Changes v6->v7:
* have look on source directory, because we use scripts for running C
API (test_zero_hugepage.sh), required for out-of-tree
