Allow init to follow symlinks when IAP/IAG install directory is configured

[steven-schattenberg-itential]

SELinux is blocking init from following symlink to the IAP install directory when it is configure to anything other than “/opt”. We may be able to install this module:

module my-node 1.0;

require {
	type init_t;
	type default_t;
	class lnk_file read;
}

#============= init_t ==============
allow init_t default_t:lnk_file read;

Test this by installing IAP in a directory other than /opt and see if SELinux fails.
