Devananda van der Veen 4115068f8b Baremetal/utils should not log certain exceptions
unlink_without_raise was logging exceptions when it failed to unlink a
file, which is confusing since it is often called on non-existing files.

create_link_without_raise was also logging exceptions when it failed
to create a symlink.

This patch corrects this behaviour; both functions now explicitly check
for the type of error they expect, and then suppress that. If another
type of OSError is encountered, a warning is logged. This patch also
adds unit tests for both functions.

fixes bug 1097931.
