RTAS: fix "Kernel Assisted Dump Memory Structure" table formatting

We currently have 5 columns where the last 2 are defined to only use
1% of the table width, causing the corresponding row entries to
overrun the table and use excessive vertical space. Define the
column widths as 1*/1*/1*/2*/2* instead, since the last 2 columns
are used for the value descriptions.
