[Buildroot] [PATCH v5 4/5] support/testing/tests/package/test_bmap_tools: new test

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

From: Nicolas Carrier <nicolas.carrier@orolia.com>

This patch implements a simple test in which a dummy file system image
is created, then `bmaptool create` and `bmaptool copy` are used to copy
it to another file.
