testing/btest: Default to HILTI_JIT_PARALLELISM=1

Browse source 
This is a rework of b59bed9d06 moving
HILTI_JIT_PARALLELISM=1 into btest.cfg to make it default applicable to
btest -j users (and CI).

The background for this change is that spicyz may spawn up to nproc compiler
instances by default. Combined with btest -j, this may be nproc x nproc
instances worst case. Particularly with gcc, this easily overloads CI or
local systems, putting them into hard-to-recover-from thrashing/OOM states.

Exporting HILTI_JIT_PARALLELISM in the shell allows overriding.
