tests: output PATH value in log files

Adjust the PATH variable for the test setup a bit later, i.e., after
'tests/init.sh' has turned on 'set -x', so that the PATH value appears
in the test logfiles.

* init.cfg (fu_path_prepend_): Wrap immediate path_prepend_ call into
this new function.
* tests/find/debug-missing-arg.sh: Use it - right after sourcing in
'tests/init.sh'.
* tests/find/exec-plus-last-file.sh: Likewise.
* tests/find/execdir-fd-leak.sh: Likewise.
* tests/find/many-dir-entries-vs-OOM.sh: Likewise.
* tests/find/name-lbracket-literal.sh: Likewise.
* tests/find/printf_escape_c.sh: Likewise.
* tests/find/printf_escapechars.sh: Likewise.
* tests/find/printf_inode.sh: Likewise.
* tests/find/refuse-noop.sh: Likewise.
* tests/find/type_list.sh: Likewise.
* tests/misc/help-version.sh: Likewise.
* tests/sample-test: Likewise.
* tests/xargs/verbose-quote.sh: Likewise.
