build-sys: try harder to shut up compiler wrt strict-aliasing
With -Wstrict-aliasing=2 we get the following warning:
libkmod/libkmod-signature.c:124:20: note: in expansion of macro 'get_unaligned'
sig_len = be32toh(get_unaligned(&modsig->sig_len));
However there's nothing wrong with it. modsig->sig_len is uint32_t and
get_unaligned in this case returns uint32_t. There's notstrict aliasing
violation.
