[Buildroot] [git commit] linux.mk: enable options for ktap

commit: http://git.buildroot.net/buildroot/commit/?id=aaef2cad852377f8ed9ac5cc3282c9741f81c7d4
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Certain tracing related options are required to be able to build ktapvm.ko, enable those.

Enable CONFIG_FUNTCTION_TRACER as otherwise, CONFIG_EVENT_TRACING won't stick. (Some
tracer needs to be enabled for this).

[Peter: add a note to ktap Config.in explaining this is done]
