[aur-general] delete package

[KESHAV P.R.]

Hi,
     Please delete grub2-btrfs
http://aur.archlinux.org/packages.php?ID=39314 . grub2-bios-bzr-exp
http://aur.archlinux.org/packages.php?ID=41055 (actual pkgname is
inside the PKGBUILD) supports btrfs booting according to upstream and
the former package is an unofficial VCS version which has been not
been updated for a few months now (upstream does not recommend the
former repo). Thanks in advance.
