Fix LibreSSL- and -version detection

[Sp1l]

Was almost correct...
LibreSSL uses X.Y.Z numbering only whereas OpenSSL uses X.Y.Za numbering (apart from first release of X.Y.Z).
This patch fixes detection of LibreSSL and the version yet keeps OpenSSL detection as intended.
OpenSSL 0.9.8zf
OpenSSL 1.0.1m
OpenSSL 1.0.2
LibreSSL 2.0.5
LibreSSL 2.1.6

OpenSSL version: major=2, minor=1, fix=6
Warning: LibreSSL found, support for LibreSSL is experimental!All modules will be installed.

OpenSSL version: major=1, minor=0, fix=1, patch=l
All modules will be installed.

OpenSSL version: major=1, minor=0, fix=2, patch=a
All modules will be installed.
(OpenSSL 1.0.2 was skipped on FreeBSD, port was upgraded from 1.0.1m to 1.0.2a)

Without a fix like this, build of openxpki-0.28.0 breaks if encounters today's libressl-2.1.6.

I will publish a new release hopefully end of this week which will contain this merge. Can you confirm that this fix on top of current develop works?

[oliwel]

@Sp1l can you please make pull requests against develop next time, that will speed up integration.

Hi Oliver. For me it looks like the latest today's commit to develop (edcec2e) is empty. It says:
"Showing 0 changed files with 0 additions and 0 deletions."
At least it does not modify the file in question ..../Makefile.PL. What I am doing wrong?

[svysh]

Meanwhile, yes I can confirm. Develop brunch (edcec2e) builds ok with libressl-2.1.6. Moreover, tests say PASS, although with lots of warnings.

[svysh]

And you may want to terminate a message with "\n" in line 118 of ..../Makefile.PL

Thanks @oliwel! Will try and remember if I create a next patch for OpenXPKI to patch the develop branch instead. (If you had told me earlier I'd have rerolled the patch for that branch :D)
