[aur-general] Package removal request

[Ranguvar]

Hello,

I just recently adopted the firefox-hg-pgo package.  Could you please delete
it?  In a few minutes I am going to upload firefox-pgo-minefield.
The name fits better with the other firefox-pgo-* packages, and it is nice
in that it is manually updated when a new Firefox HG revision passes the
Mozilla Tinderbox unit tests :)

Thanks!
