[Backport 2.5.3] [yugabyte#8496] Downgrade gperftools to 2.7

Summary:
Original revision: https://phabricator.dev.yugabyte.com/D11633
Original commit: e5d4a27

Downgrade gperftools to 2.7 to avoid hitting tcmalloc bugs (gperftools/gperftools#1204, gperftools/gperftools#1227) and because we have already extensively tested tcmalloc from gperftools 2.7.

We will still use the old Linuxbrew-based third-party archive for ASAN/TSAN builds because the new Linuxbrew-based GCC 5 third-party archive does not have a Clang 7 toolchain anymore (Linuxbrew is being removed from an increasing number of build types). But ASAN/TSAN builds are non-production and do not use tcmalloc anyway so it is OK to use an archive that has gperftools 2.8.

Also fix find_or_download_thirdparty.sh to take BUILD_ROOT into account.

Note that we are using the updated third-party URL built for the 2.4 branch here, because the previous yugabyte-db-thirdparty commit we used in the 2.5.3 branch was yugabyte/yugabyte-db-thirdparty@45c97f4, which was also used in the 2.4 branch, and had the problematic gperftools version 2.8.0. The new commit we are using is https://github.com/yugabyte/yugabyte-db-thirdparty/commits/07aad696773b3db7976568a3c827e96d8c3d24c9, with gperftools downgraded to 2.7.0.
