tests: fix handling of srcdir vs abs_srcdir for dist creation

The paths listed in EXTRA_DIST must be the targets that we define
exactly, or running distcheck can fail with stale targets -- they
should have been generated before creating the dist, but they get
updated afterwards.  This is easy to repro with:
  touch tests/testsuite.at && make distcheck

Let's split the relative & absolute path logic a bit to help with
this.  We should only use relative paths in dependency related
settings, but use absolute paths when running tools after a cd to
a different location.

Also add testsuite.list.at to the dist explicitly.  We were getting
this implicitly via testsuite depending on it, but better to list
all the files exactly.
