[aur-general] Rename request: virtinst-current -> virtinst

[Devin J. Pohly]

Requesting rename of package "virtinst-current":

https://aur.archlinux.org/packages/virtinst-current/

to "virtinst".  Name is a holdover from when the package was created (as
the original submitter explains in the comments).

Thanks!
