unix: add ErrnoName and SignalName

Browse Source 
Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.

This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.

Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

Fixes golang/go#25134
