[Libguestfs] how can I run a subset of the tests?

Disclaimer: The following advice works for libnbd and nbdkit, but I
have not tested it on libguestfs:

For automake-based projects that still use directory recursion, 'make
-C tests/luks check' will run the tests in just one subdirectory, and
'make -C path/to/dir check TESTS=name_of_test' will run just one test.

If we ever switch to non-recursive automake, or even to a different
build system (qemu and libvirt both switched to meson), then I'll have
to relearn tricks.
