www-servers/tomcat: Second stab at bug #453212 for version 6

The previous attempt didn't work because 6 doesn't resolve system
properties in the catalina.properties file. I have backported the
change from 7 to make it work.

I have also unbundled el-api.jar in line with the later versions as
per bug #558728.

Package-Manager: portage-2.2.20.1
