Revert "Add the full sofficerc for LibLO."

This reverts commit 09e0734d10d91e84012ee9e2766dbd205ffd031a.

This seemingly isn't really needed (however using the full sofficerc
avoids some warnings being printed, specifically:

warn:ucb.ucp.gio:4638:1:ucb/source/ucp/gio/gio_content.cxx:378: ignoring GError "Operation not supported" for <***RECURSION DETECTED***/log.txt>

and

warn:basic:4638:1:basic/source/uno/namecont.cxx:989: Cannot access extensions!
LIBLOK: implement getDocumentType, make doctypes unique.
