rasdaemon: ras-mc-ctl: Fix script to parse dimm sizes

Removes trailing spaces at the end of a line from
file location and fixes --layout option to parse dimm nodes
to get the size of each dimm from ras-mc-ctl.

Issue is reported https://github.com/mchehab/rasdaemon/issues/43
Where '> ras-mc-ctl --layout' reports all 0s

With this change the layout option prints the correct dimm sizes
> sudo ras-mc-ctl --layout
