sci-mathematics/snns: bump EAPI, make patches eapply, expand string length for filenames

Some strings that hold filenames or file paths were limited to 50 chars, which for
my personal use is way too short; expanded these to 256 chars.

Also bumped EAPI and fixed patche headers so that they eapply cleanly via 'patch -p1'
