Other Unix platforms (e.g. Darwin) are also affected by the Go
runtime sending SIGURG.
This patch changes how we match the signal by just looking for the
"URG" name, which should handle any platform that has this signal
defined in the SignalMap.

Do not handle SIGURG on Linux, as in go1.14+, the go runtime issues
SIGURG as an interrupt to support preemptable system calls on Linux.
This issue was caught in TestCatchAll, which could fail when updating to Go 1.14 or above;
