roachprod: update thrift artifact url for use with charybdefs

[nicktrav]

The version of Thrift used in tests that use charybdefs has
disappeared from the Apache artifacts repository that is used currently,
which causes any roachtest that depends on charybdefs to fail due to
not being able to fetch the artifact it needs.

Update the artifact URL to pull from the Apache archive instead.

Touches #78006,#78007,#78008,#78010,#78015,#78016.

Release note: None.

I shall do a manual test run across the failing tests now.

Looks like upgrading the version opened a can of worms due to incompatibilities. I think I found a more stable link to the older artifacts, so I'm going to amend this PR to use that instead.

Roachtesttest test run was successful. TFTR!
