bitbake: codeparser: Track oe.utils.conditional usage

* base_conditional was already removed from oe-core:
  http://git.openembedded.org/openembedded-core/commit/?id=0391fcad9103abca0796a068f957d0df63ab4776
  after the usage was migrated to oe.utils.conditional:
  http://git.openembedded.org/openembedded-core/commit/?id=c97acbd034532895ce57c6717ed1b3ccc7900b0d
  so we can handle just ".conditional" version

* add 1st parameter to variable dependencies, that way when you use
  FOO = "${@oe.utils.conditional('VAR', 'VALUE', 'true', 'false')"
  FOO variable will have dependency on VAR variable and you don't need
  to add FOO[vardeps] += "VAR" manually every time you use
  oe.utils.conditional

* this is similar to contains tracking from:
  https://bugzilla.yoctoproject.org/show_bug.cgi?id=3890
  http://git.openembedded.org/bitbake/commit/?id=ed2d0a22a80299de0cfd377999950cf4b26c512e
  http://git.openembedded.org/bitbake/commit/?id=0b9d117631ce909312d53b93289e61defc6be01c
  but conditional is simpler, we don't need to handle the first
  parameter as a set
