capi: Enable 'bpf' feature of main library

To the degree that is possible, we intend to only ship a single version
of blazesym-c, which means that it should have relevant features
enabled. It's generally useful to have support for the recently added
BPF program symbolization included as well, so enable the 'bpf' feature
of the main library. We also enable 'dwarf', but that's just to make it
more obvious that it's enabled, as it actually is enabled by default.
