Consolidate Linux access implementation

This patch consolidates the Linux access implementation on
sysdeps/unix/sysv/linux/access.c.  Similar to auto-generation through
syscalls.list, __NR_access is check and __NR_faccessat is used only
for newer architectures (where __NR_access is not defined).

Checked on x86_64.

	* sysdeps/unix/sysv/linux/access.c: New file.
	* sysdeps/unix/sysv/linux/generic/access.c: Remove file.
