gdb: fix null pointer dereference on missing PATH variable
When running "show" with missing PATH variable a null pointer is being
dereferenced in path_info().
path_command() correctly checks whether PATH has been set before using it.
It then calls path_info() which retrieves the variable again but fails to
perform the null pointer test on it. As a result, the application crashes with
SIGSEGV on Windows for example.
Fix this by handling the null pointer case in path_info() accordingly.
