  -----------
  [compiler-rt] Remove %T from shared object substitutions (#155302)

Given we are trying to deprecate %T and remove it, we also need to
remove it from the substitutions within compiler-rt. This is the last
remaining upstream user.

This slightly increases the complexity of using these substitutions
because now you need to create/cd into a %t.dir (specifically named
that) at the beginning of the directory, but I'm not sure that's more
knowledge than what was needed before to write a test using this
substitution. These tests also definitely were not race safe previously.
