[Buildroot] [git commit] dropbear: add options to disable wtmp / lastlog logging

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=aeea387d82fc84272ebc216665cf9aeb5567438e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Buildroot does not have wtmp or lastlog support by default so allow dropbear
to be configured to stop using them and hence to stop generating system log
error messages.

[Peter: invert to positive options, and disable by default]
