xfstests: Clean up build output

We don't need to see every compiler command line for every file that
is compiled. This makes it hard to see warnings and errors during
compile. For progress notification, we really only need to see the
directory/file being operated on.

Turn down the verbosity of output by suppressing various make output
and provide better overall visibility of which directory is being
operated on, what the operation is and what is being done to the
files by the build/clean process.

This patch only addresses the top level makefile and build rules; it
does not clean up the subdirectories - these will be addressed by a
followup patch. It also does not touch the dmapi section of the
xfstests build system.

The old style verbose builds can still be run via "make V=1 ..."
