Joe Stringer e28ff1a838 tools lib bpf: Add libbpf_get_error()
This function will turn a libbpf pointer into a standard error code (or
0 if the pointer is valid).

This also allows removal of the dependency on linux/err.h in the public
header file, which causes problems in userspace programs built against
libbpf.
