ape: return plan9 error strings from strerror()
when _syserrno() fails to map a plan9 error string to
a unix error number, we copy the plan9 error string
to the per process error buffer "plan9err" and set
errno = EPLAN9.
when strerror() is called with EPLAN9, it returns
a pointer to the plan9err buffer.
