RPM spec file fixes:

 - added a usermod call to assign a potential existing mysql user to the
   correct user group (BUG#12823)
 - Save the perror binary built during Max build so it supports the NDB
   error codes (BUG#13740)
 - added a separate macro "mysqld_group" to be able to define the
   user group of the mysql user seperately, if desired.
