Fix loopback sysctl configuration. Since gh#openSUSE/open-build-service#895 sysctl settings
for loopback device where ignored. This is considered wrong as it fails to set disable_ipv6 properly.
On top we doesn't set the ipv6/ipv4 enabled node since gh#openSUSE/open-build-service#990 causing
lo to stay in device-not-running, with net.ipv6.conf.(all|default).disable_ipv6=1.
Fixes:
Always generate the ipv4/ipv6 <enabled>true|false</enabled> node
Inherit all,default,interface sysctl settings also for loopback,
except for use_tempaddr and accept_dad sysctl's.
Consider only interface specific accept_redirects sysctl settings.
Adopt ifsysctl(5) manual page with wicked specific behavior.
