remove pointless APT_PURE from void functions

Earlier gcc versions used to complain that you should add them althrough
there isn't a lot of point to it if you think about it, but now gcc (>= 8)
complains about the attribute being present.

warning: ‘pure’ attribute on function returning ‘void’ [-Wattributes]

Reported-By: gcc -Wattributes
Gbp-Dch: Ignore
