Merge sysdeps/unix/common into sysdeps/unix

["Joseph S. Myers" <joseph at codesourcery dot com>]

The directory sysdeps/unix/common is "things which are common to both
BSD and SVR4".  Any plausible Unix target for glibc nowadays is going
to have those things - that is, they can go directly in sysdeps/unix.

All that's left in sysdeps/unix/common is syscalls.list.  I propose
this patch to eliminate the directory and merge that syscalls.list
into sysdeps/unix/syscalls.list.  (settimeofday had duplicate
identical entries in both places, the other syscalls from
sysdeps/unix/common were moved into sysdeps/unix.)  Tested x86_64,
including verifying that the built shared libraries were identical
before and after the patch.

	* sysdeps/unix/syscalls.list (adjtime): Add entry from
	sysdeps/unix/common/syscalls.list.
	(fchmod): Likewise.
	(fchown): Likewise.
	(ftruncate): Likewise.
	(getrusage): Likewise.
	(gettimeofday): Likewise.
	(setpgid): Likewise.
	(setregid): Likewise.
	(setreuid): Likewise.
	(sigaction): Likewise.
	(truncate): Likewise.
	(vhangup): Likewise.
	* sysdeps/unix/common/syscalls.list: Remove file.
	* sysdeps/unix/bsd/Implies: Don't include unix/common.
	* sysdeps/unix/sysv/linux/Implies: Likewise.
