fixed cvat startup process

[azhavoro]

Slightly improved ssh keys import

Fixed CVAT startup process if the user has umask 077 in .bashrc file.
This issue is actual only for CVAT images based on ubuntu 16.04 and not reproducible for 20.04.
The root cause is difference behavior of the ssh-add tool:

ls -la .ssh/README.md 
-rw------- 1 django django 851 Oct  8 09:54 .ssh/README.md

• for ubuntu 16.04 ssh-add asks for a passphrase, so the startup process waits for input

   ssh-add .ssh/README.md 
   Enter passphrase for .ssh/README.md:

• ubuntu 20.04 ssh-add just throws the exception:

   ssh-add .ssh/README.md 
   Error loading key ".ssh/README.md": invalid format

Motivation and context
