kcm tool fix for the keyboard output permissions

This patch adds read permission for everyone to the output files of the
kcm tool. The compiled keycharmap files need to be able to be read by
everyone. This fixes a problem at startup being unable to read the
*.kcm.bin files located at <android-root>/system/usr/keychars.
