Subject: [PATCH bpf-next v1 3/3] libbpf: fix some typos in libbpf

Hi, fix some spelling errors in libbpf, the details are as follows:

-in the code comments:
	termintaing->terminating
	architecutre->architecture
	requring->requiring
	recored->recoded
	sanitise->sanities
	allowd->allowed
	abover->above
	see bpf_udst_arg()->see bpf_usdt_arg()
