[aur-general] Delete duplicate xampp package

[Sven-Hendrik Haase]

Currently, there are two packages for xampp that do the same thing:
xampp-linux, which was there two years earlier and just xampp.
The xampp PKGBUILD is pretty much the xampp-linux PKGBUILD with
added stuff for taking care of x86_64 because the regular xampp-linux
package
will not work properly with x86_64.

Therefore, this situation is a little complicated. I propose the
deletion of the xampp package
and notification of the xampp-linux package maintainer in order to make
the package
x86_64 compatible.
