[Qemu-devel] [PULL 02/19] tests/vm: avoid image presence check and removal

["Alex Bennée" <alex.bennee@linaro.org>]

From: Cleber Rosa <crosa@redhat.com>

Python's os.rename() will silently replace an existing file,
so there's no need for the extra check and removal.

Reference: https://docs.python.org/3/library/os.html#os.rename
