gnu: elixir: Enable more tests and remove patch.

Previously, due to issues in the erlang package, many tests would fail, and
the package would also nondeterministically fail to build. This is now
fixed (by patching occurrences of /bin/sh in the erlang package), so all the
tests can be run.

* gnu/packages/elixir.scm (elixir)[source]: Remove patches.
[arguments]: Remove the fix-or-disable-tests phase. Add a new set-home phase
to set the HOME environment variable prior to running the tests.
* gnu/packages/patches/elixir-disable-failing-tests.patch: Delete this file.
* gnu/local.mk: Remove now deleted patch.

-Most of these tests fail for unknown reasons when run in the chroot
-environment of a Guix build process.
-
-Common failures are:
-
- * Mix.Shell.cmd() fails with error 130
- * The git_repo fixture cannot be found
- * Communication with spawned processes fails with EPIPE
- * Failure to copy files
