Title: Export git_attr_value

Commit 0c9eacf3d2c83256736a5bb2a240e73afd13d55f introduced the function
git_attr_value and switched the GIT_ATTR_* macros to use it, but
attempting to use that function leads to a linker error (undefined
reference to `git_attr_value'). Export git_attr_value so programs can
actually call it.
