staging/easycap: remove oss support 

remove support for OSS. OSS is being deprecated
and it is just plain headache to support both alsa and oss.

Last I broke the compilation when OSS is enabled with the patch
cdaa898b
staging/easycap: kill telltale logic

so this fixes also that issue.

Once binding to ALSA interface will be stable this option will be
