Update InnerDetector/InDetConfig/CMakeLists.txt
InDetConfig
has been failing in master_Athena_x86_64-centos7-gcc11-dbg
for a while
e.g.
https://atlas-computing.web.cern.ch/atlas-computing/links/distDirectory/gitwww/MASTERWebArea/ardoc_web_areamaster64BC7G11AthenaDbg/ARDOC_TestLog_2023-01-29T2101/InnerDetector_InDetConfig___InDetConfigConf__InDetConfigTest__m.html
Let's increase the timeout to 1000s in the hope that this test succeeds again (though this is now getting pretty slow for a unit test).
