Revert "librsvg: update to 2.48.5."

This reverts commit 7ee9e5252e.

2.48.5 introduced not trivially fixable build breakage on big
endian systems, so revert for now.

https://gitlab.gnome.org/GNOME/librsvg/-/issues/604

There isn't any important fix or feature in 2.48.5 that would make
it urgent right now.
