Libguestfs - Aug 2017 - [PATCH 1/2] configure: visually split the blocks of checks

Add sort of "headers" to split most of the logical sections of the
configure, so it is easier to get feedback on the progress of configure.

Output each path where we attempt to find 'java', so it is easier to
spot whether the location for the current OS is missing.  This also
removes the need to print the location next to the version, since the
location was already printed above.
