bug#77777: 31.0.50; find-func-tests failing because of trusted-content-p check

[Jens Schmidt]

Eshel's commit 3ee021dc19e314f6f456867ec43c25aed5cc41b8 introduced a
test on trustedness in function `find-function-search-for-symbol'.  That
seems to trigger a test failure for test
`find-func-tests--locate-macro-generated-symbols':

./src/emacs -Q --eval '(load-file "test/lisp/emacs-lisp/find-func-tests.elc")'
M-x ert RET RET

  Selector: t
  Passed:  5
  Failed:  1 (1 unexpected)
