Kir Kolyshkin 3292ea5862 pkg/seccomp: use sync.Once to speed up IsEnabled ...

It does not make sense to check if seccomp is supported by the kernel
more than once per runtime, so let's use sync.Once to speed it up.

A quick benchmark (old implementation, before this commit, after):

BenchmarkIsEnabledOld-4           37183            27971 ns/op
BenchmarkIsEnabled-4            1252161              947 ns/op
BenchmarkIsEnabledOnce-4      666274008             2.14 ns/op
