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.
