linux-user: Add missing signals in strace output

Browse source 
Some of the guest signal numbers are currently not converted to
their representative names in the strace output, e.g. SIGVTALRM.

This patch introduces a smart way to generate and keep in sync the
host-to-guest and guest-to-host signal conversion tables for usage in
the qemu signal and strace code. This ensures that any signals
will now show up in both tables.

There is no functional change in this patch - with the exception that yet
missing signal names now show up in the strace code too.
