signal: Introduce API osmo_signal_talloc_ctx_init
Otherwise applications need to use "extern void* tall_sigh_ctx" and set
it manually (that symbol is not exported in any header file) or end up
allocating struct signal_handler into the NULL talloc ctx.
API created in a similar way as already existing msgb_talloc_ctx_init(),
but without the pool_size because it's not considered necessary in this
case.
