Consolidate fallocate{64} implementations
This patch consolidates all the fallocate{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/fallocate{64}.c). It also removes the
syscall from the auto-generation using assembly macros.
The new macro SYSCALL_LL{64} is used to handle the offset argument.
Checked on x86_64, x32, i386, aarch64, and ppc64le.
* sysdeps/unix/sysv/linux/Makefile (test): Add tst-fallocate and
tst-fallocate64.
* sysdeps/unix/sysv/linux/tst-fallocate.c: New file.
* sysdeps/unix/sysv/linux/tst-fallocate64.c: Likewise.
* sysdeps/unix/sysv/linux/tst-fallocate-common.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate.c: Remove file.
* sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate64.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/fallocate.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/fallocate64.c: Likewise.
* sysdeps/unix/sysv/linux/fallocate.c (fallocate): Use SYSCALL_LL
macro on offset argument.
* sysdeps/unix/sysv/linux/fallocate64.c (fallocate64): Use
SYSCALL_LL64 on offset argument.
* test-skeleton.c (FAIL_RET): Add macro.
(FAIL_EXIT): Likewise.
(FAIL_EXIT1): Likewise.
(_FAIL): Likewise.
