Fix exit status of xzgrep when grepping binary files.
When grepping binary files, grep may exit before it has read all the input. In this case, gzip -q returns 2 (eating SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status (e.g. 141). This causes wrong exit status when grepping xz- or bzip2-compressed binary files. The fix checks for the special exit status that indicates SIGPIPE. It uses kill -l which should be supported everywhere since it is in both SUSv2 (1997) and POSIX.1-2008. Thanks to James Buren for the bug report.
