makefile: symlink-install: do not depend on realpath

For the Makefile, we can use $(PWD) make macro from make(1posix)
as POSIX requires all environment variables be accessible as
macros, and $PWD is a standard sh(1) environment variable.

lei.sh must quiet the stderr of realpath before falling back to
readlink(1) which is available on NetBSD.
