This avoids gratuitous execution of POSIX utilities in a forked shell to
do a job that python itself is perfectly capable of doing.
Note that it changes existing behavior *slightly* (but for the better),
as before this patch, even a commented out line like the following:
# enable_persistent_debug_logging=yes
... in `ifupdown2.conf` would have led to the persistent debugging
feature being enabled, despite `ifupdown2.conf`'s content suggesting
that this is against the (afaict not formally specified) parsing rules.

This patch foregoes the use of
system()to makecatandgrepdo what's better done in pure python.I've also fixed a small typo in the
ifupdown2.conftemplate that might confuse users.
