Always add 'boot_method' vmedia in redfish/ilo vmedia boot

The inclusion of a boot_method=vmedia kernel command line
argument is mandatory singnaling so IPA understands it has
been booted via virtual media, and to act accordingly.

+  - |
+    Fixes the missing ``boot_method`` ramdisk parameter for dynamicly build
+    virtual media payloads. This value must be set to ``vmedia`` for the
+    ramdisk running on virtual media to understand it is executing from
+    virtual media. This was fixed for cases where it is used with the
+    ``redfish-virtual-media`` based boot interfaces as well as the
+    ``ilo-virtual-media`` boot interface, which is where dynamic virtual media
+    deployment/cleaning ramdisk generation is supported.
