[PATCH 11/15] report: collect basic information about a test run

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Record various generic information about an fstests run when generating
a junit xml report.  This includes the cpu architecture, the kernel
revision, the CPU, memory, and numa node counts, and some information
about the block devices passed in.
