Add more ptrace constants for AArch64 and PowerPC.

Browse Source 
Linux 5.10 adds PTRACE_PEEKMTETAGS and PTRACE_POKEMTETAGS for AArch64.
Adding those shows up that glibc is also missing PTRACE_SYSEMU and
PTRACE_SYSEMU_SINGLESTEP, for AArch64 (where they were added to Linux
in 5.3) and for PowerPC (where they were added in Linux 4.20); it
already has those two defines for x86.  Add all those defines to
glibc's headers.

Tested with build-many-glibcs.py for aarch64-linux-gnu and
powerpc-linux-gnu.
