PATCH: (resubmit) make section with EntryPoint executable

[Marcus Meissner]

Hi,

One of the game cracks reportedly had the section
of the AddressOfEntryPoint in not executable.

This does not make sense, so I added a workaround for this.

Ciao, Marcus

Changelog:
	Make the section with AddressOfEntryPoint in it executable.
