[pbs-devel] [PATCH proxmox-backup 1/2] manifest: revert canonicalization to old behaviour

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

JSON keys MUST be quoted. this is a one-time break in signature
validation for backups created with the broken canonicalization code.
QEMU backups are not affected, as libproxmox-backup-qemu never linked
the broken versions.

Signed-off-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>

Note: after this has been applied and proxmox-backup has been bumped,
libproxmox-backup-qemu needs to be be re-built with the new code and
bumped for restore to work again.
