[fix](jvm) the jvm opt should only be set once

[morningman]

What problem does this PR solve?

Introduced from #47299
the SetEnvIfNecessary may be called multiple times, and in #47299,
we changed setenv("LIBHDFS_OPTS", libhdfs_opts.c_str(), 0); to setenv("LIBHDFS_OPTS", libhdfs_opts.c_str(), 1);
so it will add krb5 path at the end of LIBHDFS_OPTS and set it every time,
so LIBHDFS_OPTS becomes longer and longer.

This PR fix this issue by calling SetEnvIfNecessary only once
