[Buildroot] [PATCH] syslog-ng: use bundled libbson

[Baruch Siach]

libbson is a dependency of the mongo-c-driver that syslog-ng uses. Buildroot
doesn't package mongo-c-driver so syslog-ng uses the bundled one. The bundled
mongo-c-driver in turn may optionally use a bundled libbson. When Buildroot
builds libbson mongo-c-driver detects that and does not configure its bundled
libbson. This breaks the build of the syslog-ng mongodb module because it adds
the bundled libbson to the headers search path.

Always use the mongo-c-driver bundled libbson. Anyone concerned with the size
impact should add a standalone mongo-c-driver to Buildroot.
