Michael Orlitzky 24f21a3012 ext/imap/config.m4: fix conftest segfault in utf8_to_mutf7 check, bug #66909.
The test program for utf8_to_mutf7 attempts to call it without
arguments. The function expects one argument, however, and this leads
to a segfault as reported in PHP bug #66909.

The test program is using the PHP_IMAP_TEST_BUILD macro which
complicates things a little. To keep this diff small, the
PHP_IMAP_TEST_BUILD macro was modified to pass a fifth argument
"extra-source" to the PHP_TEST_BUILD macro. The check for
utf8_to_mutf7 was then modified to check for a dummy function,
utf8_to_mutf7_php, which passes the correct number of arguments to
utf8_to_mutf7.
