[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=1023f742b8e4213685b9e4efe23f75885482fd8d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
