QStorageInfo: allow getting the info of pseudo filesystems too

Browse Source 
They won't be listed in QStorageInfo::mountedVolumes, but we can now
obtain their info if you know their mountpoint. For example, on Linux:

 $ ./qstorageinfo /dev /proc /sys
 Filesystem (Type)            Size  Available BSize  Label            Mounted on
 devtmpfs (devtmpfs) RW    4029772    4029764  4096                   /dev
 proc (proc)         RW          0          0  4096                   /proc
 sysfs (sysfs)       RW          0          0  4096                   /sys
