* PKGBUILD:
- use release tar instead of git tag
- remove outdated dependency version requirements (not documented in
package any more)
- FIX BUG to handle symlinks when unzipping
- remove html documentation already covered by man doc in package
- additional edits
Similar to https://github.com/Alexpux/MINGW-packages/pull/2878
this adjusts the pkgbase names of all packages to match the directory
name the PKGBUILD is in.
The motivation for this is to provide links to PKGBUILD sources and
git history from the web interface.
The "dwz" directory is deleted as it just contains an older copy of the
elfutils PKGBUILD (elfutils isn't in the repo)
