release: prepare for 2.2.2 by hagitsegev

build_deb is randomly failing due to not picking up USENETWORK=yes
in the config file. Fix by switching to explicit specification of
the pbuilder configuration file, instead of hoping pbuilder will
pick it up from root's home directory.

Partial backport of cd1c79f90f247c24b96e50fadf3b0b10216fc194.

(cherry picked from commit 15aacb40fc008092ea020f5868685f0340c986c8)
