[PATCH] get_maintainer.pl: Find maintainers for removed files

[Geert Uytterhoeven]

For removed files, get_maintainer.pl doesn't find any maintainers (besides
the default linux-kernel@xxxxxxxxxxxxxxx), as it only looks at the "+++"
lines, which are "/dev/null" for removals.
Fix this by extending the parsing to the "---" lines.

E.g. for the two line test patch below the real score maintainers will now
be found:

    --- a/arch/score/include/asm/dma-mapping.h
    +++ /dev/null
