This allows developers that are interested in Capsicumizing their programs to determine where violations are being raised. Previously, CAPFAIL only produced output for processes using Capsicum(4) capabilties. Thus, most ktrace users never received log output from the trace point. With the recent changes, this is no longer the case. Having this trace point enabled by default will produce output for all processes that use syscalls that are not permitted in capability mode. This may lead to confusion for users that are not familiar with the feature. Remove KTRFAC_CAPFAIL from ktrace's default points to avoid this.
