If we're going to have a list of ntp servers, we should at least respect
them. Fallback to the original static list if no configured servers are
found.

This replaces the use of uci_validate_section() with
uci_load_validate(), which removes the need to declare local variables
for every config option.
This also moves the generated config file to /var/etc and adds a
service_triggers() function.

use ntpq to check the status of the ntp server as all other status scripts included in the ntp tarball are
based on perl which would dramatically increase the footprint of ntpd

Seems ntpdate also requires this lib:
```
Package ntpdate is missing dependencies for the following libraries:
libcap.so.2
make[2]: *** [/store/buildbot/slave/ar71xx/build/bin/ar71xx/packages/packages/ntpdate_4.2.8p4-1_ar71xx.ipk] Error 1
make[2]: Leaving directory `/store/buildbot/slave/ar71xx/build/feeds/packages/net/ntpd'

The ntpd package ships autoconf macros which attempt to test for the C99
compliance of `snprintf()` and `vsnprintf()`.
Those macros unconditionally consider the functions not compliant in a cross
compile setting and therfore break all subsequent configure tests because
the `snprintf` and `vsnprintf` symbols are shadowed with `#define` directives
redirecting them to their respectiv gnulib replacements.
The fortify source headers in turn will `#undef` those defines when wrapping
the associated functions and therfore cause all `conftest` programs to emit
a failure.
Pass the required magic autoconf cache variables via `CONFIGURE_VARS` to let
`./configure` assume C99 compliance of the affected functions, thus fixing
the build.
