_lrotl removal in libqb.cpp

Browse source 
_lrotl is defined elsewhere in the graphics routines.  By using a custom
QB64 version, it tosses definition errors with newer compiler versions.
Easiest fix:  Remove the custom _lrotl since it's only used a total of 3
times (all in the LINE routine), and do themath without the function
naturally.
