Make vendored libraries available at compile time (fixes #57)

Typo

When building, BUILD_DIR is set to a temporary directory. Vendored
libraries (e.g., pylibmc) are downloaded and unpacked in
$BUILD_DIR/.heroku/vendor/lib, but this is not currently in
LIBRARY_PATH or LD_LIBRARY_PATH.

Fix this by doing the following:

* Add $BUILD_DIR/.heroku/vendor/lib to LIBRARY_PATH/LD_LIBRARY_PATH

* Add $BUILD_DIR/.heroku/vendor/include to
  C_INCLUDE_PATH/CPLUS_INCLUDE_PATH

* Add $BUILD_DIR/.heroku/vendor/bin to PATH, so vendored commands can
  be used at compile time (e.g., curl-config)

* Add $BUILD_DIR/.heroku/vendor/lib/pkg-config to PKG_CONFIG_PATH, so
  vendored packages can be found with pkg-config

Fixing the compile hook scripts paths

The compile script is run with the root of the git repo of the project
being pushed as the working directory.

$BIN_DIR is pointing to the bin directory of the buildpack which is not
where you would want to put the pre and post compile hooks.

Changing back to the old convention of looking for the hooks from the
bin directory at the root of the project.

Use $BIN_DIR in hooks.
