[LLD][ELF] Fix compressed-debug-level test on SystemZ
The libz compression library on SystemZ by default makes use of the
platform's hardware-accelerated compression facility. This is much
faster than the regular software implementation, but often results in
slightly different outputs. This causes failures with the
compressed-debug-level test case.
To fix this, set the DFLTCC environment variable to zero while running
tests on SystemZ, which prevents use of hardware compression and falls
back to the software implementation.
