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.

On some platforms, the shell will determine what attributes a file
will have, so while the program might think it's safely outputting
binary data, it's not always true.

For the sake of the tests, it's therefore safer to use -out than to
use redirection.

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.
