[PATCH] get_maintainer: Allow usage outside of kernel tree

[Antonio Nino Diaz]

Add option '--no-tree' to get_maintainer.pl script to allow using this
script in projects that aren't the Linux kernel if they use the same
format for their MAINTAINERS file. This command is also available in
checkpatch.pl, for example.
