tools/resolve_btfids: fix build with musl libc

Browse Source 
commit 62248b22d0 upstream.

Include the header that defines u32.
This fixes build of 6.6.23 and 6.1.83 kernels for Alpine Linux, which
uses musl libc. I assume that GNU libc indirecly pulls in linux/types.h.

Fixes: 9707ac4fe2 ("tools/resolve_btfids: Refactor set sorting with types from btf_ids.h")
