Subject: test: raise fd limit to maximum before running fdpass tests
X-Git-Tag: dbus-1.15.12~8^2~1

test: raise fd limit to maximum before running fdpass tests

Many of these tests require more than the default fd limit on some systems,
so raise the limit, if we can, to give them a better chance of being able
to run.

Closes #176
