[PATCH v1] procd: Adding support to detect Pantavisor Container Platform

[Gaurav Pathak]

Modified container.h to detect the pantavisor container platform,
as it runs a custom modified version of LXC. container.h is modified
to check if procd is running in a pantavisor container environment by
detecting the presence of pantavisor directory under /.
