install.sh: avoid creating symlinks with restricted permissions 

Linux and most systems do not have symlink permissions, but some
systems, including MacOS, do, and creation of the symlink with umask
set to 0777 makes the symlink inaccessible on such systems.

clear umask when making a symlink so that the behavior is uniform.
