guix: no-longer pass --enable-glibc-back-compat to Guix

Browse source 
Now that our Guix builds are performed on glibc 2.24 and 2.27 (RISCV),
we no-longer need to pass the --enable-glibc-back-compat option.

Replace it with --disable-threadlocal, to prevent the usage of symbols
from glibc 2.18.

None of the binaries produced required symbols later than 2.17, and 2.27
(RISCV).
