Langtools_custom tests are run as hotspot_custom tests in rerun test jobs

[Haroon-Khel]

A langtools test failed in https://ci.adoptium.net/job/Test_openjdk11_hs_sanity.openjdk_aarch64_linux_testList_0/25/tapResults/

langtools_all_0
TEST: tools/javac/failover/CheckAttributedTree.java

In the rerun job https://ci.adoptium.net/job/Test_openjdk11_hs_sanity.openjdk_aarch64_linux_rerun/13/tapResults/, the test fails to rerun because its rerun as a hotspot_custom test instead of a langtools_custom test

TESTING:
Error: Cannot find file: /home/jenkins/workspace/Test_openjdk11_hs_sanity.openjdk_aarch64_linux_rerun/aqa-tests/TKG/../openjdk/openjdk-jdk/test/hotspot/jtreg/tools/javac/failover/CheckAttributedTree.java

langtools_custom rerun link is not enabled as we didn't run langtools tests before. langtools_all was enabled recently https://github.com/adoptium/aqa-tests/pull/5353/files
