Jan Beich 5483384e44 install: work around historical BSD cp(1) behavior ...

Strip ending / (slash) of the source when copying hicolor directory to
avoid installing icons under a theme with empty name. This should
unbreak expanding Icon in .desktop file by gtk_icon_theme_lookup_icon()
on DragonFly and FreeBSD.

|cp -R foo/ bar| == |cp -R foo/. bar| was disabled by NetBSD and OpenBSD
years ago to match POSIX. Other cp(1) implementations aren't affected.
