ui-snapshot: do not access $HOME
It's a bit tedious to have to do this here too. If we encounter other issues with $HOME down the line, I'll look into adding some nice utility functions to handle this, or perhaps giving up on the hope that we could keep $HOME defined for scripts. This commit additionally adds a test case, should the issue surface again. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
