ash: expand: Use HOME in tilde expansion when it is empty

Upstream commit:

    Date: Sun, 27 May 2018 17:31:57 +0800
    expand: Use HOME in tilde expansion when it is empty

    Currently if HOME is set to empty tilde expansion will fail, i.e.,
    it will remain as a literal tilde.  This patch changes it to
    return the empty string as required by POSIX.
