ptrace: use ptrace_request() in the remaining architectures
Use ptrace_request() in the three remaining architectures that didn't use it
(m68knommu, h8300, microblaze). This means:
- ptrace_request now handles PTRACE_{PEEK,POKE}{TEXT,DATA} and PTRACE_DETATCH
calls that were previously called directly, or in case of h8300 even open
coded.
- adds new support for PTRACE_SETOPTIONS/PTRACE_GETEVENTMSG/
PTRACE_GETSIGINFO/PTRACE_SETSIGINFO
