Various bootloader add kernel commandline options dynamically, filter
these out when grabbing boot options from /proc/cmdline. Specifically
grub adds BOOT_IMAGE and systemd-boot adds initrd.

If !existed, then we add arg to kargs->order, where it will be freed
by that array's free-function. However, if the kernel argument did
already exist, we have to either free arg ourselves (and make sure
the old key is what appears in the hash table), or do a linear search
on kargs->order to replace the old key with the new.
Leak found by valgrind memcheck.

Add command line arguments:
--import-proc-cmdline: import values from /proc/cmdline
--merge: import current values
--replace=ARG=VALUE: replace value
--append=ARG=VALUE: append a new argument
Extra command line arguments are treated like --append=, which
gives backwards compatibility.

The "ordered hash" code was really just for kernel arguments. And it
turns out it needs to be a multihash (for e.g. multiple console=
arguments).
So turn the OstreeOrderedHash into OstreeKernelArgs, and move the bits
to split key=value and such into there.
Now we're not making this public API yet - the public OstreeSysroot
just takes char **kargs. To facilitate code reuse between ostree/ and
libostree/, make it a noinst libtool library. It'll be duplicated in
the binary and library, but that's OK for now. We can investigate
making OstreeKernelArgs public later.
