runtests: set SOURCE_DATE_EPOCH to fix failing around midnight

vszakats · vszakats · commit 58772b0e082e · 2024-07-16T02:13:48.000+02:00
To make sure that `managen` called by test 1706 uses the same date as the test expects in the `%DATE` macro. Before this patch when tests started running before UTC midnight and reached test 1706 after, these dates were different and the test failed. Follow-up to 0e73b69 Fixes #14173 Closes #14187
