powerpc: Update AT_HWCAP2 bits

Linux commit ID cba6ac4869e45cc93ac5497024d1d49576e82666 reserved a new
bit for a scenario where transactional memory is available, but the
suspended state is disabled.

	* sysdeps/powerpc/bits/hwcap.h (PPC_FEATURE2_HTM_NO_SUSPEND): New
	macro.
	* sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add
	htm-no-suspend.
