Add a arm target_signal.h to complete the files currently in the tree. The arm
directory isn't compiled, so it was missing target_signal.h. Update it to the
same level as x86 and sparc. This was abstracted from the target_arch_vmparam.h
file in the bsd-user branch.

Shall we just wait until arm actually compiles?
This won't, being a copy from x86...

OK. Fair point. I'll drop this for now and pick it up when more of the arm
is in place. Good catch.
