NetBpfLoad: remove specified(pin_subdir) checks 
pin_subdir is now always specified...

Of the 4 checks, 2 are only for ALOGV low-value logging,
I've always thought we should probably just remove that.

The other 2 checks appear to actually be buggy.
They should probably be checking selinux_context rather
than pin_subdir, since pin_subdir likely (untested)
just works fine.

Verify via:
  git grep 'specified[(]pin_subdir[)]'

Long term goal here is to eliminate 'prefix' entirely.
This will also allow merging all the bpf .o's into 1.

NetBpfLoad: Prevent libbpf log truncation 
The liblog logger truncates messages over 1024 bytes, which was
cutting off kernel verifier logs.

This change bypasses the limit by splitting the log by newline
and logging each line individually.

NetBpfLoad: suppress debug log if NETBPFLOAD_VERBOSE_LOG is not defined 
Reduces ~900 lines of log spam by suppressing non-warning messages.
