[RFC PATCH] meson: Only install ROMs when building system emulation binaries

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

It is pointless to install ROM blobs for user emulation.

RFC because I think it would be better to make the 'blobs'
option a 'feature' instead of a boolean so we can set it
as 'auto' and then in that case we could do something

  blobs = have_system

because currently ./configure still displays:

                    Install blobs: YES

which is confusing.
