Remove the runtime dependency on lsb_release
We have attempted to remove this dependency before as it pulls in various other dependencies and it would be nice to be rid of it if possible. Noe that it would remain as a buldtime dependency.
AFAICT we only call this in lsb_release_parse at runtime and, with modern releases we should be able to make do with the call to os_release_parse only which uses /etc/os-release and it should be available on most (all?) releases we support.
