e1_input: Use osmo_use_count in e1inp_line
osmo_use_count is available since libosmocore 1.1.0 release, so bump
required libosmocore version in autotools and packages.
struct e1inp_line field refcnt is kept in order to keep ABI
compatibility accessing struct fields. The new use_count is added at the
end. Size of struct changing is fine since it is allocated through
an API and a pointer should be used by clients.
e1inp_line_clone API is changed but it's not used by anyone outside
libosmo-abis, so it's fine.
