package/efl: fix -fno-common build failure

Added upstream patch for fixing build failure when using GCC10 as a host
compiler (-fno-common is now default).

+Subject: [PATCH] Fix build with gcc 10 (which has -fno-common enabled by
+ default).
+
+EFL failed to build from source in Fedora Rawhide as a result of the update to GCC 10. GCC 10 enables -fno-common by default, and this found three issues in EFL:
+
+  # The eina benchmark code defined int key_size in a header that was included in multiple places.
+  #/usr/bin/ld: bin/elementary/elementary_test-test_ui_clock.o:(.bss.dt1+0x0): multiple definition of `dt1'; bin/elementary/elementary_test-test_datetime.o:(.bss.dt1+0x0): first defined here
+ The elementary test code defines the "dt1", "dt2", "dt3" vars in two code files which are compiled together (but these variables do not appear to be used globally)
+  # The eio test code defines the "ee" var in two code files which are compiled together (but this variable does not appear to be used globally)
+
+I've fixed these issues and confirmed locally that the code builds again in Fedora.
