doc: Copy {bsc,bts}.adoc from osmo-gsm-manuals

Those adoc files are only used by osmo-bsc.git and openbsc.git
(osmo-nitb), and the later is deprecated and no longer maintained, which
means new features are only added to BSC. Hence it makes no sense to
keep the doc shared between both. As a result, they will be dropped from
osmo-gsm-manuals.git and we keep an unmodified copy here.
