[igt-dev] [PATCH i-g-t] Replaced get_current_dir_name() with getcwd() for BSD compatibility

[Jake Freeland]

The get_current_dir_name() function is a GNU C extension that copies
the current directory's absolute path into a memory allocated buffer.
This patch replaces get_current_dir_name() with a POSIX compliant
getcwd() that performs the same action.
