[PATCH] Support nullglob in profile.*.in files

["Martin Liška" <mliska@suse.cz>]

In openSUSE we have the following RPM checker that uses
shopt -s nullglob:
https://github.com/openSUSE/post-build-checks/blob/master/checks/50-check-libtool-deps#L31

The script loads all /etc/profile.d/*.sh files via source $FILE which
can end up by stuck cat (with no arguments):

shopt -s nullglob ; cat "/etc/debuginfod"/*.urls
(stuck)
