Make __ASSUME_UTIMES hppa-specific.

This patch makes __ASSUME_UTIMES hppa-specific, removing mentions of
the macro from architecture-independent code and code for other
architectures.  (All other architectures either have the utimes
syscall in all relevant kernel versions, or use the asm-generic
interface so only have utimensat and won't get the utimes syscall.)  A
similar approach is used to that used for futimesat for MicroBlaze: if
the kernel is recent enough that the utimes syscall can be assumed to
be present, use the implementation in terms of the utimes syscall, and
otherwise use the linux/generic implementation in terms of utimensat.

Tested x86_64 that the disassembly of installed shared libraries is
unchanged by the patch.  Not tested for hppa.

	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Do
	not define.
	* sysdeps/unix/sysv/linux/utimes.c: Do not include
	<kernel-features.h>.
	(__utimes) [__NR_utimes]: Make code unconditional.
	(__utimes) [!__ASSUME_UTIMES]: Remove conditional code.
	* sysdeps/unix/sysv/linux/aarch64/kernel-features.h
	(__ASSUME_UTIMES): Do not undefine.
	* sysdeps/unix/sysv/linux/tile/kernel-features.h
	(__ASSUME_UTIMES): Likewise.
	* sysdeps/unix/sysv/linux/hppa/kernel-features.h
	(__ASSUME_UTIMES): Define for [__LINUX_KERNEL_VERSION >= 0x030e00]
	instead of undefining for [__LINUX_KERNEL_VERSION < 0x030e00].
	* sysdeps/unix/sysv/linux/hppa/utimes.c: New file.
