[Buildroot] [git commit] package/jpeg: convert to the virtual-package infrastructure

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=5e82185537209962a6d6283e2ea898eff8129271
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since this package is implemented via a choice rather than the usual
separate-package providers, we only need BR2_PACKAGE_HAS_JPEG to be
always defined when the 'jpeg' package is selected.
