unified build scheme: adjust test framework for out of source build tree

To be able to run tests when we've built in a directory other than
the source tree, the testing framework needs a few adjustments.

test/testlib/OpenSSL/Test.pm needs to know where it can find
shlib_wrap.sh, and a number of other tests need to be told a different
place to find engines than what they may be able to figure out on
their own. Relying to $TOP is not enough, $SRCTOP and $BLDTOP can be
used as an alternative.

As part of this change, top_file and top_dir are removed and
srctop_file, bldtop_file, srctop_dir and bldtop_dir take their place.

Change OpenSSL::Test to be an extension of Test::More

It became tedious as well as error prone to have all recipes use
Test::More as well as OpenSSL::Test. The easier way is to make
OpenSSL::Test an extension of Test::More, thereby having all version
checks as well as future checks firmly there. Additionally, that
allows us to extend existing Test::More functions if the need would
arise.

Add math tests recipes

The math recipes are among the heavier, but also quite important.
For the BN test, we have previously relied on bc to verify the numbers.
Unfortunately, bc doesn't exist everywhere, making tests on some platforms
rather painful. With the new recipe (recipes/10-test_bn.t), we rely
on perl's Math::BigInt and a homegrown simple calculator (recipes/bc.pl)
that can do enough to cover for bc.
