Really we need to fix the inheritance to make
BpfMapRO the parent class of BpfMap:
but that's a far more difficult thing to do,
so in the short term we punt like this.
This makes BpfMapRO a little bit more usable,
and allows a slow transition across the codebase...

not perfect due to this being in a header file, so multiple copies
potentially exist, but it's really simple, and works nearly as well.

We switch back to int from ParcelFileDescriptor,
and eliminate all calls to close(). Bpf Map FDs
now live till process exit.

TCA_U32_ACT was missed when converting from the u32 filter to matchall.
Interestingly, cls_matchall does not seem to validate this type as the
kernel happily accepted this configuration (which absolutely should not
happen as TCA_U32_ACT is greater than __TCA_MATCHALL_MAX).

The art apex already has access to bpf_headers which includes bpf_syscall_wrappers,
but this extra line is needed to switch it away from needlessly linking libbpf_android.
Since these are header files only, this annotation is kind of pointless,
but it does turn out to be needed...

The bpf_headers no need to explicitly specify visibility for
system/netd/libnetdbpf. The libnetdbpf depends on
bpf_connectivity_headers, which exports bpf_headers already.
