Fix building x86_64 on Android.

Missed a define in x64MemTools for when the thought process was Android == ARM
Also changes the variable we use for choosing which folders to copy to and from our jni file.
This has changed since the x86_64 build target uses the library folder x86-64, which is stupid and annoying.

Gameini cleanup.

This is a cleanup of the gameini database. Specifically:
It removes the "Issues=..." lines and their respective comments since
they don't show up in the gui, are very old and wrong in most cases.
They contain probably more than 4 year old comments (i don't have a clue
who or when wrote them).
Also remove the "EFBCopyCacheEnable = True" lines from the database.
These were put at a time that efb to Ram had resolution issues without
cache being enabled, safe texture cache could be disabled and speed was
detrimental. Now that efb to ram doesn't have the same res issues as
back then, safe texture cache can't be disabled with speed gains being
non existent (you get even a speed hit if texture cache is put to safe)
i think it should be removed from the database.
