Arcade dats don't show that parent roms also need samples

I noticed the following with fbalpha dats but it applies to all arcade dats. Reference: https://github.com/libretro/fbalpha/issues/105#issuecomment-271067873
I noticed it with cheekyms, as the game has no clones and the fact that the game needs samples wasn't marked, as its sample isn't being mentioned in the header:

<game name="cheekyms">
		<description>Cheeky Mouse</description>
		<year>1980</year>
		<manufacturer>Universal</manufacturer>
		<rom name="cm03.c5" size="2048" crc="1ad0cb40"/>
		<rom name="cm04.c6" size="2048" crc="2238f607"/>
		<rom name="cm05.c7" size="2048" crc="4169eba8"/>
		<rom name="cm06.c8" size="2048" crc="7031660c"/>
		<rom name="cm01.c1" size="2048" crc="26f73bd7"/>
		<rom name="cm02.c2" size="2048" crc="885887c3"/>
		<rom name="cm07.n5" size="2048" crc="2738c88d"/>
		<rom name="cm08.n6" size="2048" crc="b3fbd4ac"/>
		<rom name="cm.m9" size="32" crc="db9c59a5"/>
		<rom name="cm.m8" size="32" crc="2386bc68"/>
		<rom name="cm.p3" size="32" crc="6ac41516"/>
		<sample name="squeek" />
		<sample name="hammer" />
		<sample name="sqeekdead" />
		<sample name="two" />
		<sample name="squeek2" />
	</game>

Samples of parent roms should be mentioned as well like this:
<game name="cheekyms" sampleof="cheekyms">

Start by comparing the arcade DAT output for fbalpha, especially the cheekyms entry and its sample declarations. Update the generation or data path so parent ROM sample requirements are represented in the game header, then verify the resulting XML uses the requested sampleof attribute consistently across arcade DATs.
