php7: upgrade to 7.2.4

* For changes, see:
http://www.php.net/ChangeLog-7.php#7.2.4

* Remove patches as they've been upstreamed:
- 0001-Specify-tag-with-libtool.patch
- CVE-2017-16642.patch
- CVE-2018-5711.patch

* mcrypt module has been deprecated and as such dependency has been moved
from php.inc to php5 recipe.

* Refresh patches to avoid fuzz warnings.

* New patches to:
- Make sure libxml is detected using pkg-config instead of binconfig.
- Fix link time warnings (backport, see patch for details)

* Move the following patches to php5 from inc as they were getting applied
out of context:
- acinclude-xml2-config.patch
- 0001-acinclude-use-pkgconfig-for-libxml2-config.patch
