configure: Detect kcov support and introduce CONFIG_KCOV
kcov is kernel code coverage tracing tool. It requires kernel 4.4+
compiled with certain kernel options.
This patch checks if kcov header "sys/kcov.h" is present on build
machine, and stores the result in variable CONFIG_KCOV, meant to
be used in linux-user code related to the support for three ioctls
that were introduced at the same time as the mentioned header
(their definition was a part of the first version of that header).
