update-alternatives: fix the sed pattern in remove_alt

'\>' is to matches the end of a word, but the executable is
not always a 'word', e.g. /usr/lib64/busybox/usr/bin/[

then such alternatives can not be removed.

So change to use '\s' in the pattern since the following
character of the $path is whitespace.
