QStorageInfo/Unix: exclude invalid volumes from mountedVolumes()

Browse Source 
Invalid are usually those mounted on a filesystem we can't access:

$ df /run/user/0/gvfs
df: /run/user/0/gvfs: Permission denied
$ ./qstorageinfo /run/user/0/gvfs
Could not get info on /run/user/0/gvfs

df already doesn't include it by default:

$ df | grep -c gvfs
0

But we were:

$./qstorageinfo | sed -n '1p;/gvfs/p'
Filesystem (Type)                        Size  Available BSize  Label   Mounted on
gvfsd-fuse (fuse.gvfsd-fuse)    RW          0          0     0          /run/user/0/gvfs

Note also how this is showing a total size of 0, which is usually the
type of filesystem we exclude. It's actually -1 but got rounded down to
0 when we divided by 1024.

Pick-to: 6.6
