Mark run-ptrace-mapper and run-ptrace-misc as XFAIL on MIPS

Browse source 
Though PTRACE_SINGLESTEP is defined on MIPS Linux, the kernel does
not support that kind of request. The ptrace call failed and sets
errno to EIO and paused process is not resumed. In case of
run-ptrace-mapper and run-ptrace-misc this leads to hanged execution
because next call to wait4 never returns.

This change adds run-ptrace-mapper and run-ptrace-misc to the list
of 'expected failed' tests on MIPS targets.
