[Buildroot] [git commit branch/2018.08.x] package/netplug: fix quoting of ${NETWORKING} in init script

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1b0dfb76037c303e4b6474d1f82f0674d5a329ca
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.08.x

Since 4adaa581b27dc27298eb7cc421ee8f530f88e18e, S29netplug looks for
/etc/default/network instead of /etc/sysconfig/network.  When this
file exists but does not define $NETWORKING, the script fails on line
29 with something like:

/etc/init.d/S29netplug: 29: [: =: unexpected operator

Fix quoting so this error no longer happens.

[Thomas: keep double quotes around "no", keep curly braces when
referencing the variable.]
