Simplify jhbuild moduleset after update to Ubuntu 26.04

[clopez]

It seems that after we update to Ubuntu 26.04 we can remove a big part of this moduleset because the versions of this libraries on Ubuntu are now the same or even higher than we are shipping.

I tested this diff on top of PR #239 and it seems to be working fine:

Please keep libsoup just for convenience of hacking on it, and we'll likely continue using newer versions of it over time, but it doesn't need to be built by default.

Same for glib/glib-networking really. It's nice to work on them with a single command.

Incorporated both comments in PR-239.

@clopez Is it OK to replace sccache with Ubuntu's, its going from version 0.14.0 to 0.13.0 but AFAICT that version was only chosen because it was newer not because we needed it.
