vpnor: partition: Add write permissions to writable files

The code preserves the file permissions when the partition files are
copied to the writeable area. Currently the file permissions are 664,
but if the squashfs was built with file permissions set to 444 to
make it explicit that the pnor partition files were read-only, the
files in the writable area would also have read only permissions.

Therefore, explicitly add write permissions to the partition files
that are copied to the writable area.

Tested:

- With current permissions (there's no change):

root@witherspoon-YL30UF74T02M:~# ls -l /var/lib/phosphor-software-manager/pnor/ro/HBD
-rw-rw-r--    1 253760   401855     1179648 Sep 23 16:30 HBD
root@witherspoon-YL30UF74T02M:~#ls -l /var/lib/phosphor-software-manager/pnor/rw/HBD
-rw-rw-r--    1 root     root       1179648 Oct  9 18:38 HBD

- With read-only permissions:

root@witherspoon-YL30UF74T02M:~# ls -l /var/lib/phosphor-software-manager/pnor/ro/HBD
-r--r--r--    1 root     root       1179648 Oct  9 15:33 /var/lib/phosphor-software-manager/pnor/ro/HBD
root@witherspoon-YL30UF74T02M:~# ls -l /var/lib/phosphor-software-manager/pnor/rw/HBD
-rw-r--r--    1 root     root       1179648 Oct  9 18:43 /var/lib/phosphor-software-manager/pnor/rw/HBD
