Remove linux go build constraint for uffd (#8042)

We don't need the go build constraint because the BUILD file contains a
`target_compatible_with` platform. This makes it easier to edit the file
with an IDE, even on non-linux platforms

This was originally added here
#7965, then reverted due
to the separate changes in that PR
