Subject: [PATCH] scripts: get_maintainer.pl, remove \xa0 from the script

My perl v5.24.0 complains when running the get_maintainer.pl script as
follows:
Unrecognized character \xA0; marked by <-- HERE after <-- HERE near column 1 at ./scripts/get_maintainer.pl line 277.

It is weird to have ascii non-breaking spaces in a script, so do:
s/\xa0/ /g
