dev-cpp/libmcpp: Add missing patches

* r3 include two new patches already in debian distributions, and mcpp forums.
  - libmcpp-2.7.2-zeroc: patch is required for dev-libs/Ice to work propertly
  - libmcpp-2.7.2-gniibe: patch include two simple security fixes

Closes: https://github.com/gentoo/gentoo/pull/7820

+Description: Simple fixes
+ * Fix freeing unmalloced memory
+   The memory of 'in_file' is not malloced, but points to argv[].
+   It is wrong to free it.
+ * When there is no input file specified by argv, it causes error
+   and fp_in == NULL.  Check is needed to call fclose for fp_in.
