This reverts commit 1cc3868955. The
previous commit (hopefully) works around the libomp bugs that caused
Clang builds to fail.

Clang tests are hitting this assertion in libomp (libomp5-10
1:10.0.0-4ubuntu1):
Assertion failure at kmp_tasking.cpp(501): taskdata->td_flags.tasktype == 1.
OMP: Error #13: Assertion failure at kmp_tasking.cpp(501).
OMP: Hint Please submit a bug report with this message, compile and run commands used, and machine configuration info including native compiler and operating system versions. Faster response will be obtained by including all program sources. For information on submitting this issue, please see https://bugs.llvm.org/.
Disable Clang builds until we figure out what's going on.

With the added Clang tests, apparently vmtest is generating excessive
traffic on Dropbox. Disable it on GitHub Actions until I can work out a
new solution.

Everytime I try to build drgn with Clang, there are a few things that
need fixing. Let's test it so that it stays in good shape.

We currently bundle a version of elfutils with patches to export
additional stack tracing functionality. This has a few drawbacks:
- Most of drgn's build time is actually building elfutils.
- Distributions don't like packages that bundle verions of other
packages.
- elfutils, and thus drgn, can't be built with clang.
Now that we've replaced the elfutils DWARF unwinder with our own, we
don't need the patches, so we can drop the bundled elfutils and fix
these issues.

Apparently the package index can be out of date on the newly brought up
VM, leading to 404s, so make sure to update it first.

Travis CI is no longer offering free open source CI, so migrate to
GitHub Actions. The only downside is that GitHub Actions doesn't support
nested virtualization, but we can work around that by falling back to
slow emulation.
