php74.extensions.iconv: fix error signalling

The configure script checks whether iconv supports errno. Unfortunately, on PHP < 8, the test program includes $PHP_ICONV_H_PATH, which defaults to FHS path so it fails to build:

	conftest.c:13:10: fatal error: /usr/include/iconv.h: No such file or directory
	   13 | #include </usr/include/iconv.h>
	      |          ^~~~~~~~~~~~~~~~~~~~~~

That causes the feature check to report a false negative, leading PHP to use a degraded code that returns PHP_ICONV_ERR_UNKNOWN when error occurs, breaking granular error handling in applications.

To prevent this, let’s just include <iconv.h>.

PHP 8 just uses include path so the detection works there: 7bd1d70341
