Subject: [PATCH 1/6] Fixes for the /root/.profile file: - Fixed the issue when
 installing the LinuxRMM-Script the /root/.profile PATH variable is incorrect.
 - Added a check_profile function to check the integrity of the /root/.profile
 PATH variable and correct any issues it my find. Running the update function
 will correct the profile as well.
