Subject: [PATCH] Remove unused in_addr_t type alias (#12994)

The fastcgi code was refactored in
18cf4e0a8a574034f60f4d123407c173e57e54ec and in_addr_t is no longer
used. The PHP_CHECK_IN_ADDR_T is also obsolete and not recommended way
to discover availability of the type. If needed in the future, the
AC_CHECK_TYPES can be used instead.
