Subject: [PATCH] ctest_configure: Restore handling of relative
 CTEST_BINARY_DIRECTORY

In commit e52eada2c2 (cmCTestConfigureCommand: Refactor command line
construction, 2025-01-28, v4.0.0-rc1~60^2~2) we switched from the
`BuildDirectory` setting, which was always an absolute path, to
`CTEST_BINARY_DIRECTORY`.  Convert it to an absolute path too.

Fixes: #27026
