Using the linker's --wrap feature has the downside that it only covers
references across object files: If foo.c defines a() and b(), with b
calling a, --wrap=a does nothing to that call.
Instead, use objcopy to mark a weak and global so it can be overridden
by another implementation, but only for files originating in src/.
That way mocks - implemented in tests/ - become the source of truth.
TEST=Had such an issue with get_log_level() in a follow-up commit, and
the mock now takes over. Also, all existing unit tests still pass.

The current test framework builds the test code without any warnings at
all, which isn't great -- we have already slipped in some cases of
non-void functions not returning a defined value, for example. It would
likely be overkill to try to use all the same warnings we use for normal
coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's
__wrap_xxx() mock functions unnecessarily cumbersome to work with, and
other things like -Wvla may be appropriate for firmware but is probably
too aggressive for some simple test code). Therefore, let's just add
some of the stuff that points out the most obvious errors.

<cmocka.h> requires a few standard headers to be explicitly included
before itself or it will throw compilation errors. Having to always
include these headers in the right order in every test is cumbersome.
Instead, this patch encapsulates the problem in a new <tests/test.h>
header that all tests should include (instead of <cmocka.h> directly).
Also fix --gc-sections in the test framework which needs to be passed
for linking, not for compiling.
