linux-user: Special-case ERESTARTSYS in target_strerror()

Browse Source 
Since TARGET_ERESTARTSYS and TARGET_ESIGRETURN are internal-to-QEMU
error numbers, handle them specially in target_strerror(), to avoid
confusing strace output like:

9521 rt_sigreturn(14,8,274886297808,8,0,268435456) = -1 errno=513 (Unknown error 513)
