Pull up following revision(s) (requested by tsutsui in ticket #1152):

        sys/arch/hp300/conf/RAMDISK: revision 1.16
        sys/arch/hp300/conf/INSTALL: revision 1.66

Remove options (NVNODE, NBUF, and BUFPAGES) for small RAM machines.

These options make extracting binary sets much slower even on miniroot.

Instead, use "options BUFCACHE=5" (use 5% of memory for buffercache) and
also specify "-fno-unwind-tables" for COPTS to shrink INSTALL kernel.

Worth to pullup to netbsd-9.
