util/abuild: Update syntax from 'function func' to 'func()'

Abuild used a mix of 'function funcname' and 'funcname()`. This
standardizes them all to use the 'funcname()' format. While they do
the same thing, we should be consistent across the file, and the
'funcname()' syntax is generally preferred.
