kdump-lib.sh: add a config format and read helper
Add a helper `kdump_read_conf` to replace read_strip_comments.
`kdump_read_conf` does a few more things:
- remove trailing spaces.
- format the content, remove duplicated spaces between name and value.
- read from KDUMP_CONFIG_FILE (/etc/kdump.conf) directly, avoid pasting
"/etc/kdump.conf" path everywhere in the code.
- check if config file exists, just in case.
Also unify the environmental variable, now KDUMP_CONFIG_FILE stands for
the default config location.
This helps avoid some shell pitfalls about spaces when reading config.

fadump: isolate fadump initramfs image within the default one
In case of fadump, the initramfs image has to be built to boot into
the production environment as well as to offload the active crash dump
to the specified dump target (for boot after crash). As the same image
would be used for both boot scenarios, it could not be built optimally
while accommodating both cases.
Use --include to include the initramfs image built for offloading
active crash dump to the specified dump target. Also, introduce a new
out-of-tree dracut module (99zz-fadumpinit) that installs a customized
init program while moving the default /init to /init.dracut. This
customized init program is leveraged to isolate fadump image within
the default initramfs image by kicking off default boot process
(exec /init.dracut) for regular boot scenario and activating fadump
initramfs image, if the system is booting after a crash.
If squash is available, ensure default initramfs image is also built
with squash module to reduce memory consumption in capture kernel.
