signal.7: Add signal numbers for parisc 

This patch adds the signal numbers for parisc to the signal(7) man page.

Those parisc-specific values for the various signals are valid since the
Linux kernel upstream commit ("parisc: Reduce SIGRTMIN from 37 to 32 to
behave like other Linux architectures") during development of kernel 3.18:
