Tiezhu Yang a4a5d4ee06 libbpf: Add __NR_bpf definition for LoongArch

LoongArch uses the generic syscall table, where __NR_bpf is defined
as 280 in include/uapi/asm-generic/unistd.h.

To align with other architectures, add the __NR_bpf definition for
LoongArch to avoid a potential compilation failure: "error __NR_bpf
not defined. libbpf does not support your arch."

This is a follow up patch of:

  commit b0c47807d3 ("bpf: Add sparc support to tools and samples.")
  commit bad1926dd2 ("bpf, s390: fix build for libbpf and selftest suite")
  commit ca31ca8247 ("tools/bpf: fix perf build error with uClibc (seen on ARC)")
  commit e32cb12ff5 ("bpf, mips: Fix build errors about __NR_bpf undeclared")
