[meta-selinux][dunfell][patch 2/4] audit: set correct security context for /var/log/audit

[Armin Kuster <akuster808@gmail.com>]

From: Yi Zhao <yi.zhao@windriver.com>

By default /var/log is a symbolic link of /var/volatile/log. But
restorecon does not follow symbolic links then we will encounter the
following error when set /var/log/audit directory:

$ /sbin/restorecon -F /var/log/audit
/sbin/restorecon: SELinux: Could not get canonical path for /var/log/audit restorecon: Permission denied.

Use readlink to find the real path before set security context.
