scripts/sanitizer-env.sh: remove incorrect $CC quotes

On Arch (at least) the shell chokes when the CC variable contains space,
for the given construct - $("$CC" foobar).

Since we variable is likely to contain the executable and arguments, the
quotation is wrong. Drop it and ultimately resolve the LD_PRELOAD
issues... That said, the tests still fail over here, segfault-ing in (or
due to) the LD_PRELOAD library init-modules.so.

Fixes: f5b4ff82 ("Add support for clang sanitizers")
Fixes: c7686797 ("scripts/sanitizer-env.sh: support new clang 19 DSO")
