progress: use 'encoding.trim' to trim output line correctly

Before this patch, 'progress' extension trims output line by directly
slicing byte sequence, but it may split at intermediate multi-byte
sequence.

This patch uses 'encoding.trim' to trim output line correctly, even if
it contains multi-byte characters.

"rm -f loop.pyc" before changing "loop.py" in "test-progress.t"
ensures that re-compilation of "loop.py", even if "loop.py" and
"loop.pyc" have same timestamp in seconds.
