simplify substitute_path_rule_matches using filename_ncmp
At the time this function was written, there was no filename_ncmp, only FILENAME_CMP. So, in order to do an n-cmp, we had to make a local copy of the first n characters of our string and use that to perform the comparison. This patch simplifies the function's implementation, now that we have filename_ncmp. gdb/ChangeLog: * source.c (substitute_path_rule_matches): Simplify using filename_ncmp instead of FILENAME_CMP. Tested on x86_64-linux.
