[PATCH v2 libinput 3/5] test: allow running the symbols-leak-test.in script directly

[Peter Hutterer]

With autotools, we replace the @top_srcdir@ during configure and then run
the resulting scripts.

With meson, it's easier to just pass top-srcdir it in as argument.

Changes to v1:
- use a case statement to check the first character for @ to check whether
  it was replaced
