VLCRemoteBrowsingTVCell: Add .intValue highlighted by static analyzer

Xcode identified what it believes are four cases of integer comparison
without the necessary .intValue method for converting the NSNumber to an
integer for the comparison to succeed.

Each case does appear to be correctly identified, so this adds four
instances of .intValue matching similar cases elsewhere in the codebase.
