btf_encoder: Fix signed/unsigned comparision 

Since the 'int' variable, 'err' was just checked for < 0, cast it to
uint32_t and compare with the 'uint32_t' one.

Fixes this clang warning:

  /var/home/acme/git/pahole/btf_encoder.c: In function ‘btf_encoder__write_raw_file’:
  /var/home/acme/git/pahole/btf_encoder.c:890:17: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
    890 |         if (err != raw_btf_size) {
        |                 ^~
