[Ada] Spurious error on overriding protected function in instance
The conformance between an overriding protected operation with
progenitors and the overridden interface operation requires subtype
conformance; requiring equality of return types in the case of a
function is too restrictive and leads to spurious errors when the return
type is a generic actual.

* sem_ch6.adb (Check_Synchronized_Overriding): The conformance
between an overriding protected operation and the overridden
abstract progenitor operation requires subtype conformance;
requiring equality of return types in the case of a function is
too restrictive and leads to spurious errors when the return
type is a generic actual.

* gnat.dg/prot6.adb, gnat.dg/prot6.ads: New testcase.
