linux-user: Renumber TARGET_QEMU_ESIGRETURN, make it not arch-specific

Browse source 
Currently we define a QEMU-internal errno TARGET_QEMU_ESIGRETURN
only on the MIPS and PPC targets; move this to errno_defs.h
so it is available for all architectures, and renumber it to 513.
We pick 513 because this is safe from future use as a system call return
value: Linux uses it as ERESTART_NOINTR internally and never allows that
errno to escape to userspace.
