URLs update
In generals.ent, all "common" URLs are changed to HTTPS.
Bzip2 homepage is added.
Elfutils, kbd, and util-linux homepage are modified to a "real" homepage,
instead of a downloading directory.
http://psmisc.sourceforge.net/ redirects to GitLab.
Now most URLs are HTTPS. The remaining "unsafe" download locations:
file-5.39.tar.gz (it can be downloaded from GitHub, but the package from
GH needs autoreconf -fi), self-hosted packages at anduin, and patches at
http://www.linuxfromscratch.org/ (should be fixed after gimli migration).
git-svn-id: svn://svn.linuxfromscratch.org/LFS/trunk@12152 4aa44e1e-78dd-0310-a6d2-fbcd4c07a689
