fwk_log: remove '\n' character from log prints
Created by: leandro-arm
Currently, newline characters are optionally added to log messages even though fwk_log
appends its own FWK_LOG_TERMINATOR
string. This change removes the redundant newlines, improving the efficiency of log output and simplifying the logging code by eliminating the need for newline search functions.
