base-files: Create webos_cryptofsdir

:Release Notes:
Create the initial /media/cryptofs directory.

:Detailed Notes:
Drop work around for /media/internal permissions, it's already fixed in
package.bbclass in meta-webos-backports.

Also, put back the parent directory of ${webos_db8datadir}/temp into
dirs700 so that it has the desired permissions.

:Testing Performed:
Only build tested and verified in buildhistory.

:QA Notes:
No functional change in image.

:Issues Addressed:
[GF-36175] base-files should create /media/cryptofs
