Autotools: Remove obsolete config.status invocations (php#15185)

This was once added to fix the bug https://bugs.php.net/13561 because
the phpize and php-config scripts were located in the pear subdirectory
and were installed only when --with-pear option was used. Then in the
20c4328 scripts were moved to scripts
subdirectory with this mechanism used in the generated Makefile when
running 'make install' command.

Before the AC_CONFIG_FILES was introduced to Autoconf AC_OUTPUT once
accepted arguments. This signature is obsolete in current Autoconf
versions.

The old obsolete config.status invocation:
  CONFIG_FILES=... ./config.status

And the new invocation is (if used with AC_CONFIG_FILES in the code):
  ./config.status --file=...

Instead, this simply removes the redundant phpize and php-config
generation with the old obsolete config.status invocations as these
files are always generated in the php-src build context.
