scripts/gdb: ensure the absolute path is generated on initial source

Browse Source 
Post 'make scripts_gdb' a symbolic link to scripts/gdb/vmlinux-gdb.py is
created.  Currently 'os.path.dirname(__file__)' does not generate the
absolute path to scripts/gdb resulting in the following:

    (gdb) source vmlinux-gdb.py
    Traceback (most recent call last):
      File "scripts/gdb/vmlinux-gdb.py", line 25, in <module>
	import linux.utils
    ModuleNotFoundError: No module named 'linux'

This patch ensures that the absolute path to scripts/gdb in relation to
the given file is generated so each module can be located accordingly.
