Update Stale Links from Sourceforge to github

[james-prior]

Need to update multiple old links from sourceforge to github. For example,

https://libcheck.github.io/check/web/install.html has links to a
mailing list on sourceforge.
Is there a current mailing list,
or should we use issues
and pull requests?

More candidates for updating are revealed with:

grep -ri sourceforge .

Thanks for pointing this out. I found a few places which need to be updated, namely:

$ grep -ri sourceforge . | grep -v cunit | grep -v check-devel | grep -v NEWS | grep -v check-users | grep -v cppunit |  grep -v junit | grep -v ChangeLog | grep -v check.sourceforge.net/ns | grep -v aceunit | grep -v embunit | grep -v check_unittest.xslt | grep -v flex | grep -v daimonin | grep -v exip | grep -v expat | grep -v AUTHORS | grep -v cutest | grep -v mingw

As for the Sourceforge mailing lists, those are still active and if a user has a question about Check I'll respond to them there. Pull requests and issues on GitHub are also fine.

I'll update the links mentioned above to point to GitHub.
