user/xmlsec: fix tests, add -gcrypt and -gnutls, and more

* URL changed to official website.
* Source changed to official download URL instead of GitHub archive.
* Tests were being skipped spuriously due to the test suite being
  broken. The relevant commits to fix this have been backported and
  applied.
* Add the -gnutls (for experimental/aqbanking) and -gcrypt (required in
  order to build -gnutls) subpackages.
* The *.la files have been removed from the main package (remove
  options=libtool). It is assumed these are no longer needed, since the
  only official reverse dependency at this time is libreoffice, which
  uses pkg-config and not libtool.
* usr/lib/libxmlsec1-nss.so was moved to -dev by running the -dev split
  function before the plugin split functions.
* usr/lib/xmlsec1Conf.sh was moved to -dev.

Bump and fix experimental/firefox-esr

This MR bumps experimental/firefox-esr to 60.6.1 ESR (the latest release at this time), and updates the LLVM dependency to LLVM 7. Two new patches are required: the first fixes for building with Rust 1.33.0, as the build will fail due to undocumented macros, which I believe is a change in the behaviour of the `deny_docs` compiler pragma from 1.31.x; the second (courtesy of @aranea) fixes mozbuild to actually disable the profiling code when the `--disable-profiling` flag is passed in `mozconfig`, which otherwise fails to compile due to musl incompatibility.

Build succeeds on `x86_64` with beta3 Rust and on `aarch64` with beta2 Rust. Resulting package appears to work on both platforms, as my test boxen could both load https://adelielinux.org and play youtube videos.
