Specify path of LASEM_LIB_DIR for Linux #78

Allegedly to fix https://github.com/asciidoctor/asciidoctor-mathematical/issues/30, but CI is failing.

I can see it fails on ruby 2.1 on macOS, all rubies on Linux passed. Shall we just fix the path on Linux? The error message seems to not be related with the library path, though.

Failed to parse mtex

The solution doesn't work in Linux if mathematical is installed system-wide with bundle install using a non-root account. In that case bundle install the gem in a temporary directory (later copy it to its final path) so LASEM_LIB_DIR and RPATH points to the temporary path, not to the directory where the gem will be installed.

A workaround is to install mathematical with gem (or install it locally, of course).
