Subject: [PATCH] Compile time no longer available

A few functions still attempted to extract the "compile time"
of each module. This info used to be available when calling
Module:module_info but was removed "a long time ago". A first
removal was done in OTP-15330 and this removes some remaining
leftover cases.
