libpcap: patch to add limits.h to pcap-usb-linux.c

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
This is an upstream-applied patch that fixes 'PATH_MAX' and 'NAME_MAX'
undeclared when compiling on musl with CONFIG_PCAP_HAS_USB.

[aafa351] pcap-usb-linux.c: add missing limits.h for musl systems.
