[aur-general] Deletion request: jhbuild-git_2

[郑文辉(Techlive Zheng)]

[jhbuild-git_2][1] is duplicated to package [jhbuild-git][2], please
delete [jhbuild-git_2][1].

The later [jhbuild-git][2] couldn't be built for a while in th past
(not the case now, it has been updated), user @spirtbrat uploaded his
fix as a new package with a nameing like "*_2" instead of trying to
get the [jhbuild-git][2] fixed, but this is not how AUR works.
