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 b0c47807d31d ("bpf: Add sparc support to tools and samples.")
commit bad1926dd2f6 ("bpf, s390: fix build for libbpf and selftest suite")
commit ca31ca8247e2 ("tools/bpf: fix perf build error with uClibc (seen on ARC)")
commit e32cb12ff52a ("bpf, mips: Fix build errors about __NR_bpf undeclared")
