breakpoint.c: fix libc probe scan when no get_longjmp_target exists.
As discussed on the GDB ML[1], libc probes for longjmp were not being
loaded if a custom <arch>_get_longjmp_target function was not
implemented.
This is trivially fixed by moving the 'if (!gdbarch_get_longjmp_target_p
(gdbarch))' down, just bellow libc probe code and above the per-objfile
cache lookup.
While the condition could also be removed altogether with no
side-effects, it is in fact an optimization to avoid searching for
symbols if the arch doesn't provide support for get_longjmp_target().
This has been tested on PPC and PPC64.

* breakpoint.c (create_longjmp_master_breakpoint): Allow libc
probe scan even when the arch provides no get_longjmp_target.
