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

[Philippe Waroquiers <philippe.waroquiers@skynet.be>]

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).
