Bug#439197: Build-depends libpri-dev version not specific enough

[Martijn Grendelman]

Package: asterisk
Version: 1.4.11~dfsg-1

Asterisk 1.4.11~dfsg-1 uses a patch named "use-libpri-bristuffed", that
makes the build process depend on a version of libpri-dev that supplies
the file "/usr/include/bristuffed/libpri.h". If this file is not
present, the build fails.

/usr/include/bristuffed/libpri.h is present in libpri-dev 1.4.1-1 and
up, but not in 1.4.0-2 and before.

Asterisk build-depends on libpri-dev (>= 1.4). I think this should be
changed to (>= 1.4.1).
