etc/systemd/zfs-mount-generator: avoid strndupa
The non-standard strndupa function is not implemented by musl libc,
and can be dangerous due to its potential to blow the stack.  (musl
_does_ implement strdupa, used elsewhere in this function.)

With a similar amount of code, we can use a heap allocation to
construct the pool name, which is musl-friendly and doesn't have
potential stack problems.

(Why care about musl when systemd only supports glibc?  Some distros
patch systemd with portability fixes, and it would be nice to be able
to use ZFS on those distros.)
