dracut-kdump.sh: make it POSIX compatible
POSIX doesn't support keyword `local`, so this commit reduced variable usage. Heredoc ("<<<") operation is also not supported, so kdump.conf is now pre-parse into a temp file. Also fixes many POSIX syntax errors. Signed-off-by: Kairui Song <kasong@redhat.com> Acked-by: Philipp Rudo <prudo@redhat.com>
