[U-Boot] [PATCH 3/8] buildman: patman: Fix -H when installed as a symlink

[Simon Glass]

It is convenient to install symlinks to buildman and patman in the search
patch, such as /usr/local/bin. But when this is done, the -H option fails to
work because it looks in the directory containing the symlink instead of its
target. Fix this.
