The `struct selabel_digest` member `hashbuf_size` is used to compute
hashes via `Sha1Update()`, which takes uint32_t as length parameter
type. Use that same type for `hashbuf_size` to avoid potential value
truncations, as the overflow check in `digest_add_specfile()` on
`hashbuf_size` is based on it.
label_support.c: In function ‘digest_gen_hash’:
label_support.c:125:53: warning: conversion from ‘size_t’ {aka ‘long unsigned int’} to ‘uint32_t’ {aka ‘unsigned int’} may change value [-Wconversion]
125 | Sha1Update(&context, digest->hashbuf, digest->hashbuf_size);
