[PATCH RFC next 02/18] CI: pass clang HOSTCC and CC to pytest

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

test_env_initial_env_file test calls make on the build directory passed
with --build-dir parameter which points at UBOOT_TRAVIS_BUILD_DIR which
is populated with buildman before pytest is run. For "sandbox with clang
test.py" and "sandbox64 with clang test.py" jobs, buildman uses clang-20
toolchain, but pytest isn't configured to use that as well, resulting in
gcc being used with a configuration made with clang-20 toolchain.

Specify the HOSTCC and CC clang make arguments so pytest uses the proper
toolchain, this will be required in a few commits when we'll upgrade to
a newer version of scripts/Makefile.extrawarn which gets rid of checking
whether a clang flag exists (because it's supported by the min clang
version the kernel advertises as being supported) which will be an issue
since GCC for sure doesn't support all clang flags.
