[rpcd PATCH 1/4] rc: fix and improve script scanning START and STOP

Currently we stop searching at the first occurence of START or STOP
entry. This is wrong since we totally miss the other data (START or
STOP) in the occurence of the other.

Fix and improve script scanning by:
- Increase the line max length to 255 char to read it in one go.
- Scan only the first 10 lines.
- Don't stop at the first occurence and try to search also for the other
  data.
