runsc: fix the local timezone support in logs

This patch fixes the local timezone support in logs by creating
etc/localtime in the rootfs of sandbox process and gofer process
based on the current /etc/localtime on host.

Before this patch, the timestamps in sandbox and gofer logs will
fallback to UTC timezone after execving "/proc/self/exe" which
may not be very convenient for users to analyse the logs:
