Replace local bootc-kernel-cmdline crate with linux-kernel-cmdline

The kernel command line parsing crate has been split out into a
separate repository and published to crates.io as
linux-kernel-cmdline. Replace the local copy with the published
version 0.1.1.

The two bootc-specific constants (INITRD_ARG_PREFIX and ROOTFLAGS)
that were defined in the local crate's lib.rs are not part of the
published crate. These already had local definitions in
bootc_kargs.rs, so update install.rs to use those instead.
