This fix tries to address the issue raised in #24374 where
`docker info` outputs seccomp support in Ubuntu 14.04 but
the seccomp wass not actually supported.
The issue is that in the current docker implementation, seccomp
support is only checked against the kernel by inspect CONFIG_SECCOMP
and CONFIG_SECCOMP_FILTER. However, seccomp might not be enabled
when building docker (through golang build flag).
This fix adds a supportSeccomp boolean variable. The supportSeccomp
is only set to true when seccomp is enabled when building docker.
This fix fixes#24374.

Fixes#23031
If a profile is explicitly passed but the system is not built with seccomp support,
error out rather than just running without a profile at all as we would previously.
Behaviour is unchanged if no profile is specified or unconfined is specified.
