perl: Rework use and exporter declarations

Place 'use' strict and warnings first, then Exporter 'our' declarations,
then Test module imports, then system module imports, then Dpkg module
imports, then 'use' parent and overload pragmas, separated by a blank
line for each block.

Split each exported symbol declaration into its own line to ease
modifications.
