initramfs-framework: Allow directories with spaces

When mdev module loads the Linux kernel modules, it can visit
directories with spaces. To allow that, we must quote the variable
otherwise it misunderstand it arguments as multiple entries.

Fixes:

,----
| Freeing unused kernel memory: 3072K (80d00000 - 81000000)
| cat: can't open '/sys/devices/platform/Vivante': No such file or directory
| cat: can't open 'GCCore/modalias': No such file or directory
`----
