Dmitry V. Levin 7bbf8b54cd tests: fix TEST_SYSCALL_{NR,STR} and STRUCT_STAT_STR macros for musl
The contents of TEST_SYSCALL_NAME and STRUCT_STAT macros was subject
to macro expansion when used in definitions of TEST_SYSCALL_NR,
TEST_SYSCALL_STR, and STRUCT_STAT_STR macros.

As some libcs, e.g. musl libc, define lfs64 names as macros
(stat64 as stat, lstat64 as lstat, etc.), this might result to incorrect
expansion of TEST_SYSCALL_NR, TEST_SYSCALL_STR, and STRUCT_STAT_STR
macros.  To avoid this problem, define these macros directly and remove
TEST_SYSCALL_NAME macro.

* tests/_newselect.c (TEST_SYSCALL_NAME): Remove.
(TEST_SYSCALL_NR, TEST_SYSCALL_STR): New macros.
* tests/fcntl.c: Likewise.
* tests/fcntl64.c: Likewise.
* tests/fstat.c: Likewise.
* tests/fstatat64.c: Likewise.
* tests/lstat.c: Likewise.
* tests/newfstatat.c: Likewise.
* tests/select.c: Likewise.
* tests/stat.c: Likewise.
* tests/fstat64.c (TEST_SYSCALL_NAME): Remove.
(TEST_SYSCALL_NR, TEST_SYSCALL_STR, STRUCT_STAT_STR): New macros.
* tests/lstat64.c: Likewise.
* tests/stat64.c: Likewise.
* tests/fstatx.c (TEST_SYSCALL_NR, nrify, nrify_): Remove.
* tests/lstatx.c: Likewise.
* tests/struct_flock.c (TEST_SYSCALL_NR, TEST_SYSCALL_STR, nrify,
nrify_, stringify, stringify_): Remove.
* tests/xselect.c: Likewise.
* tests/xstatx.c: Check TEST_SYSCALL_STR instead of TEST_SYSCALL_NAME.
(STRUCT_STAT_STR, TEST_SYSCALL_STR, stringify, stringify_): Remove.
[!STRUCT_STAT] (STRUCT_STAT_STR): New macro.
