tar: CVE-2022-48303

Fixes CVE-2022-48303 by checking Base-256 encoding is at least
2 bytes long. GNU Tar through 1.34 has a one-byte out-of-bounds
read that results in use of uninitialized memory for a conditional
jump. Exploitation to change the flow of control has not been
demonstrated. The issue occurs in from_header in list.c via a
V7 archive in which mtime has approximately 11 whitespace characters.
