build-appliance-image: Fix incorrect PATH
When modifying the PATH variable in .bashrc, double quote characters
were used, resulting in expanding the variable $PATH with the value of
PATH of the system building the Build Appliance.
The original intent was to enter an un-expanded (literal) $PATH.
In order to that, one must use single quotes instead of double quotes.
