Build web filter modules for ARM

[filippo_carletti]

@denis.robel

/usr/lib/squid/ssl_crtd -c -s /var/lib/ssl_db

This command is automatically run when you save the configuration, see /etc/e-smith/events/actions/nethserver-squid-conf.
The problem is that the ARM squid package has a different path:

1. x86 = /usr/lib64/squid/ssl_crtd
2. arm = /usr/lib/squid/ssl_crtd

Luckily, the nethserver-squid-conf is the only place where ssl_crtd is called, we may have a fix trying both path.
I’ll create a pull request, it may be accepted.

hack the template file for ufdbGuard.conf in that way that all categories in ACL are in double quotes

My mistake, I fixed the double quotes issue only partially.
