mkdumprd: fix patterns to modify mount options

mkdumprd removes "noauto" mount option, but it also mistakenly removes
"noauto" within a string. For example ext4 has mount option noauto_da_alloc
mkdumprd will replace it with _da_alloc.

Use '\b' to match a whole word of "noauto" to fix it.
Also do same for s/ro/rw for same reason.
