libbpf_android doesn't use libnetdutils

Remove libnetdutils dependency because bpf is being used for things other
than networking these days, and we don't want to make libnetdutils
vendor-available in the future. libbase provides an alternative type now.

Bug: 140330870
Test: atest netd_integration_test netd_unit_test libnetdbpf_test
Test: atest bpf_benchmark (fails on unrelated synchronizeKernelRCU)
