Subject: [PATCH] tests: additional tests of stat decoders

* tests/fstatx.c (IS_FSTAT): Define to 1.
* tests/fstatat64.c [__GLIBC__ && __sparc64__] (TEST_BOGUS_STRUCT_STAT):
Define to 0.
* tests/xstatx.c [!IS_STAT] (IS_STAT): Define to 0.
[!TEST_BOGUS_STRUCT_STAT] (TEST_BOGUS_STRUCT_STAT): Define to 1.
(main): Add a check for non-available pointer and a check
for block device file.
* tests/statx.sh: Add tracing of /dev/full file, specify alignment.
* tests/fstat.test: Specify alignment.
