[PATCH 2/2] test-lib-functions: use user's TERM and HOME for 'debug'

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The 'debug' function in test-lib-functions.sh is used to invoke a
debugger at a specific line in a test. It inherits the value of HOME and
TERM set by 'test-lib.sh': HOME="$TRASH_DIRECTORY" and TERM=dumb.

Changing the value of HOME means that any customization configured in a
developers' debugger configuration file (like $HOME/.gdbinit or
$HOME/.lldbinit) are not available in the debugger invoked by
'test_pause'.

Changing the value of TERM to 'dumb' means that colored output
is disabled in the debugger.

To make the debugging experience with 'debug' more pleasant, leverage
the variables USER_HOME and USER_TERM, added in the previous commit, to
set HOME and TERM before invoking the debugger.
