Stop using PKG_OPTIONS.clamav as the options variable.

In 2005, this package started using PKG_OPTIONS.clamav instead of the
expected PKG_OPTIONS.p5-Mail-ClamAV, on the theory that the options
were the same.  Now, clamav supports "milter" and
"clamav-experimental", and p5- supports "curl".  So there's \ 
no way to
build this package with the curl option, and no way to build this
package if clamav has any options set.  Therefore, the change being
committed will not bother anyone :-)  Nevertheless, bump PKGREVISION.
