[PATCH v4 1/7] scripts/make_fit: limit .cmd file parsing to the savedcmd_ line

[Luis Augenstein <luis.augenstein@tngtech.com>]

The command is always stored in the first line of the .cmd file. Read
only the first line, so remaining lines cannot get misparsed once
.cmd files record additional fields.
