[RFA] Fix step-over-syscall.exp matching regexp for $bpnum.$locno matching

[RFA] Fix step-over-syscall.exp matching regexp for $bpnum.$locno matching

[Philippe Waroquiers]

step-over-syscall.exp has some specific tests for gdbserver.
The regexp matching breakpoint hit must take the added locno into account.

Test re-run in 3 modes (normal, native-gdbserver and native-extended-gdbserver).

I would suggest using the $::bkptno_numopt_re form (and removing the
global declaration), that makes it clear on use that this is a global
variable.  With that fixed:

Thanks for the review.
