  libpcap: fix CVE-2025-11961 OOBR/OOBW in pcap_ether_aton

Backport the fix from libpcap 1.10.6: replace the simple unbounded
loop in pcap_ether_aton() with new helper functions that validate the
input format before allocation, preventing out-of-bounds read and write
when a caller passes a malformed MAC-48 address string.

Based on commit b2d2f9a9 from the-tcpdump-group/libpcap.
