Tom Tromey 30c01bb104 Restore previous sigmask in gdb.block_signals ...

Tom de Vries found a bug where, sometimes, a SIGCHLD would be
delivered to a non-main thread, wreaking havoc.

The problem is that gdb.block_signals after first blocking a set of
signals, then unblocked the same set rather than restoring the initial
situation.  This function being called from the DAP thread lead to
SIGCHLD being unblocked there.

This patch fixes the problem by restoring the previous set of signals
instead.
