releasetools/arm_sdimage.sh: Improvements

Browse source 
- Added the possibility to define the number of parallel jobs from the
   command line with (example, default is 1):
   $ JOBS=8 ./releasetools/arm_sdimage.sh

 - Generate filesystem filling the reserved partition area, instead of
   being smaller.

 - Added a possibility to specify additional parameter to the build.sh
   script from the command line with (example):
   $ BUILDVARS='-N0 -V MYVAR=yes' ./releasetools/arm_sdimage.sh
