mk-pxelinux-ramfs: fix escaping kexec appends

Browse Source 
Currently multiple entries in a single append is broken by how the
shell in busybox escapes them. No usual grouping with " or ' will
work but calling them directly but without the --append in the
variable will let busybox do the right thing.
