tests/CheckThatTheyAllAssertOut: Ignore igortest marker function

When compiling with instrumentation igortest adds a function to mark the
file as instrumented. But as we require all functions in the file to
assert out this makes the test case fail with [1]:

  0: is false. Assertion "FAIL()" failed in AnalysisFunctionPrototypeTests#CheckThatTheyAllAssertOut (UTF_AnalysisFunctionPrototypes.ipf, line 43)

    ? Function IUTF_TagFunc_bd1f27ca745da4aa90f393ef89b21e4aa84abb5a97b8b36526b552cdeffad1d2_IGNORE

Therefore we have to remove these tag functions from our function list.

Broken since 2d62af6 (MIES_AnalysisFunctionPrototypes.ipf: Assert out, 2024-10-22).
