Add lsb_release file to "Recommends:" of rpm spec

Actually add this to the rpm spec file, as was originally intended in
atom#25541.

This helps the bug report feature of the "notifications" package
include more system info on Linux systems -- if /usr/bin/lsb_release
is available, it will be called to gether some basic OS info to add to
the bug report info.
