[PATCH V2] scripts: fix the sys path for gdb scripts

[yalin wang]

we insert __file__'s real path into sys.path,
so that no matter we import the vmlinux-gdb.py from $OUT floder or
from source code folder, we can always find the linux/ lib folder,
and we don't need create link to linux/*.py files,
remove the related make file.
