kdump-lib-initramfs.sh: prepare to be a POSIX compatible lib
Move all functions needed in the second kernel from kdump-lib.sh
to kdump-lib-initramfs.sh, and update shebang headers.
Now, kdump-lib-initramfs.sh is an independent lib script, no longer
depend on kdump-lib.sh, and kdump-lib.sh is no longer needed for
the second kernel.
In later commits, functions in kdump-lib-initramfs.sh will be reworked
to be POSIX compatible, kdump-lib.sh will contain bash only functions.
POSIX shell have very limited features, eg. `local` keyword doesn't
exist in POSIX but we rely on that heavily. So kdump-lib.sh will
use bash syntax and contain the most complex helper and codes.
kdump-lib-initramfs.sh will contain the minimum set of helpers,
and be shared by both the first and second kernel.
