fix(xCAT-server): stop the EL10 installer reserving a crash kernel riscv64 cannot use

Browse Source 
EL10 defines no default crash kernel reservation for riscv64, so the
installer's kdump add-on falls back to writing the literal
"crashkernel=auto" into the boot loader arguments of the installed
system. EL10 kernels dropped support for that value: nothing is
reserved, but the string is on the command line, so kdump.service passes
its condition and then fails on every installed riscv64 node.

Turn the add-on off in the riscv64 templates. Nodes come up with kdump
inactive instead of failed, and a node that should take crash dumps gets
a real reservation the usual way, through linuximage.addkcmdline or
bootparams.addkcmdline.
