 Testsuite: run tests in <testdir>.run instead of /tmp

 As discussed in Phab:D1187, this approach makes it a bit easier to
 inspect the test directory while working on a new test.

 The only tests that needed changes are the ones that refer to files in
 ancestor directories. Those files are now copied directly into the test
 directory.

 validate still runs the tests in a temporary directory in /tmp, see
 `Note [Running tests in /tmp]` in testsuite/driver/runtests.py.

 Update submodule hpc.
