Upgrade netty-tcnative to 2.0.61.Final

This updates the version of boringssl and removes the dependency on APR.
netty-tcnative 2.0.56.Final uses APR 1.7.0, so is in scope for
CVE-2021-35940, CVE-2022-28331, and CVE-2022-24963. netty-tcnative is
not actually vulnerable. The binary does not include apr_socket_sendv(),
apr_encode_*(), apr_pencode_*(), apr_decode_*(), apr_pdecode_*(). The
binary does include apr_time_exp_*() but it is unused code.
Unfortunately --gc-sections wasn't used during compilation.
apr_time_now() is used, but that just calls gettimeofday() and is not
vulnerable.

There's no panic here, but this updates netty-tcnative just a few weeks
before we would have ordinarily done so. Bumping the version makes life
easier for everyone.
