[PATCH 4/6] i18n win32: add git-stash eval_gettext variable prefix

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the eval_gettext() invocations to use the GIT_I18N_VARIABLE_
prefix for variables used in eval_gettext. On Windows environment
variables are case insensitive, so e.g. $PATH clashes with $path. By
using a sufficiently unique prefix we work around that issue.
