Add libsipwise-base-perl, libstrictures-perl + libperl5i-perl to Build-Depends

NOTE: libsipwise-base-perl is coming from the following repository:

deb http://deb.sipwise.com/autobuild/ wheezy-libs main
Add required packages to inc/Local/Module/Build.pm, update Build-Depends, skip dh_auto_test

Addressing the following build errors:

1) Indirect call of method "method" on object "wait_socket" at inc/Local/Module/Build.pm line 8.
2) Indirect call of method "child" on a block at inc/Local/Module/Build.pm line 49.
3) Indirect call of method "try" on a block at inc/Local/Module/Build.pm line 67.

During package build time dh_auto_test currently fails:
http://paste.mgm.sipwise.com/show/327/ - needs investigation
by developers, but this should at least give us package builds
against Debian/wheezy.
