selftests/thermal: remove duplicate newlines in perror calls 

perror() automatically appends a newline character, so the explicit '\n'
in the format strings is redundant and results in duplicate newlines in
the output.

Remove the redundant '\n' characters from perror() calls in
workload_hint_test.c to fix the formatting.
