[PATCH 2/2] systemtap: rationalise dependencies

[Ross Burton <ross.burton@intel.com>]

Boost is an optional dependency but avoid build non-determinism by adding it as
DEPENDS.  It is only for the shared pointer types so can be disabled explicitly
if required.

Turn sqlite into a PACKAGECONFIG.

Add a patch for the "monitor" feature to control the optional dependencies on
ncurses and json-c. Previously this was enabled for target only but enable it
everwhere now that json-c is available for native/nativesdk.

Of course all of this was predicated about systemtap needing systemtap-native to
be built, but it turns out that this dependency is due to oe-core 507bd2 which
adds systemtap-native as DEPENDS for convenience.  Remove this dependency, if
the user wants systemtap-native then they can build it explicitly.
