BUG/MINOR: cache: alloc shctx after check config

When running haproxy -c, the cache parser is trying to allocate the size
of the cache. This can be a problem in an environment where the RAM is
limited.

This patch moves the cache allocation in the post_check callback which
is not executed during a -c.

This patch may be backported at least to 2.0 and 1.9. In 1.9, the callbacks
registration mechanism is not the same. So the patch will have to be adapted. No
need to backport it to 1.8, the code is probably too different.
