[PATCH] catch: check for any of catch and catch2

[Uri Lublin <uril@xxxxxxxxxx>]

Catch2 is now in upstream (github) and Fedora (since Fedora 27)

Signed-off-by: Uri Lublin <uril@xxxxxxxxxx>
---

Since v3 (local only):
  - Use AC_CHECK_HEADERS instead of AC_CHECK_HEADER
Since v2:
  - Do not assume the .h files are under /usr/include
Since v1:
  - Check both Catch2 and Catch
