makepkg : allow to specify a download filename

A source entry can now have the following form, to specify a different
filename :
"filename::http://path/to/file"

Of course, the old syntax is still supported :
"http://path/to/file"

And as before, in the second case, the filename used is simply "file".

This fixes FS#11292, because handling multiple source files with the same
name is now possible (just choose a different filename).

But it will also allow to deal much more nicely with funny url like this by
using a sane filename (and unfortunately, there are quite a few) :
