fix: for exporters to work for build config, there may be two include…

… dirs For CMake / pkg-config configuration files to be used for an uninstalled build, the include directory in the build directory isn't enough, if that one is separate from the source directory. The include directory in the source directory must be accounted for too. This includes some lighter refactoring of util/mkinstallvars.pl, with the result that almost all variables in builddata.pm and installdata.pm have become arrays, even though unnecessarily for most of them; it was simpler that way. The CMake / pkg-config templates are adapted accordingly. Reviewed-by: Neil Horman <[email protected]> Reviewed-by: Tomas Mraz <[email protected]> (Merged from openssl#24918)
