option: Allow multiple options in --disable-effects

Commit 82c367 added checks that the value passed to --disable-effects
is valid, but it does not take into account that it's perfectly valid
to pass multiple values separated by commas. This commit splits
the value passed to --disable-effects and checks each component separatey.

Fixes rhbz#955277
