Subject: [PATCH] - skip BOOT_IMAGE param when copying the cmdline to BLS
 snippets

The bootloaders add a BOOT_IMAGE parameter that is present in the kernel
command line exposed via the /proc/cmdline virtual file. If this param
is added to the kernel cmdline in the BLS snippet, it will be duplicated.

Resolves: #1782321
