target/i386: Fix memory leak in sev_read_file_base64()
In sev_read_file_base64() we call g_file_get_contents(), which
allocates memory for the file contents. We then base64-decode the
contents (which allocates another buffer for the decoded data), but
forgot to free the memory for the original file data.
Use g_autofree to ensure that the file data is freed.
Fixes: Coverity CID 1459997
