Fix buffer underflow in add_path
Address sanitizer pointed out a buglet in source.c:add_path.
In this test, from gdb.base/source-dir.exp:
(gdb) set directories :/foo:/bar
... 'p[-1]' will result in a buffer underflow.
This patch fixes the bug by introducing a new check.

* source.c (add_path): Check 'p' before using 'p[-1]'.
