Both tests require the test image to have a specific size; this cannot
be guaranteed by vpc (unless tuning the test specifically for that
format).
It is safe to exclude vpc from 004 because what is tested there is
implemented in a generic part in the block layer and not
format-specific.
It is safe to exclude vpc from 104 because for vpc basically every image
size is "unaligned", so if that would break at some point in time, we
would quickly notice just by running the generic tests.

_make_test_img sets up an NBD server, _cleanup_test_img shuts it down;
thus, _cleanup_test_img has to be called before _make_test_img is
invoked another time.
Furthermore, the pipe through _filter_test_img was unnecessary;
_make_test_img already takes care of that.
And finally, a filter is added to _filter_img_info to replace
"nbd://127.0.0.1:10810" by "TEST_DIR/t.IMGFMT", since the former is the
way to express the full image path (normally the latter) for NBD tests.

Currently the file size requested by user is rounded down to nearest
sector, causing the actual file size could be a bit less than the size
user requested. Since some formats (like qcow2) record virtual disk
size in bytes, this can make the last few bytes cannot be accessed.
This patch fixes it by rounding up file size to nearest sector so that
the actual file size is no less than the requested file size.
