agent: fix start container failed when dropping all capabilities

Browse Source 
When starting a container and dropping all capabilities,
the init child process has no permission to read the exec.fifo
file because the parent set the file mode 0o622. So change the exec.fifo file mode to 0o644.

fixes #1913
