Misc: acrnctl: hot fix acrnctl bug

Browse Source 
Currently, while there is no running post-launched User VM and
user executes acrnctl command, he or she will get failure and
error message is "/run/acrn/mngr doesn't exist".

Root cause of this failure is acrnctl only check whether the folder
"/run/acrn/mngr" exist or not, if this folder doesn't exist, will
report failure.
acrnd service will create the folder "/run/acrn/mngr", user should
make sure acrnd service is started before using acrnctl

This patch will update log message while the folder "/run/acrn/mngr"
doesn't exist.

v1-->v2:
	Update log message to make it clearer.

Tracked-On: #6991
