Eric Biggers 7c68ed5c5a fsverity: Fix silent truncation in bpf_get_fsverity_digest()

bpf_get_fsverity_digest() silently truncates the digest if the provided
buffer is too small.  This is a footgun, and it doesn't match the
semantics of the equivalent UAPI (FS_IOC_MEASURE_VERITY).

Change it to return -EOVERFLOW instead, matching FS_IOC_MEASURE_VERITY.

Fixes: 67814c00de ("bpf, fsverity: Add kfunc bpf_get_fsverity_digest")
