Remove real time signals references

At this moment uksignal doesn't support real time signals (signal codes greater than 31). However, Go runtime assumes that it does and it tries to init signals up to SIGRTMAX, causing any go application to fail. This commit avoids this situation. These changes should be removed when real time signals support will be added to uksignals. Signed-off-by: Răzvan Vîrtan <virtanrazvan@gmail.com>
