intern: fold into fluxion-data and version the so

problem: the libintern so wasn't being versioned, causing problems on
upgrades, see #1308

solution: the real dependency should be on libfluxion-data anyway, which
was closer to how we wanted it.  The libintern library is now built
static, linked into libfluxion-data, and provided that way.

Additionally, the libfluxion-data library is installed as
`libfluxion-data.so.{version without git suffix}` and linked as
`libfluxion-data.so.{version major}.{version minor}` with no unsuffixed
link installed.
