crypto: strip unwanted space from openssl version

Remove trailing " \n" from `process.versions.openssl`.

d3d6cd3e was incorrectly printing this trailer, but because the
target buffer size was claimed to be the length of the version string,
the trailer was truncated off.

9ed4646d corrected the target buffer size, but then the trailer
started to appear in process.versions.

Added a test to check for regressions.
