Do not hexify binary data to compare them, do compare
them directly. That simplifies the check code and save
memory.

In test functions calling mbedtls_test_unhexify(), change the
type of the associated parameters from `char*` to `data_t`.
That way the `unhexify` operation is done by the test
framework and not by the unit test code.
Use for the new parameters of type data_t the name of the
local variable that use to store the `unhexify` version of
the `char*` parameter.

In preparation of changing the type of some parameters
of test_hkdf() from `char *` to `data_t` to get rid of the
calls to mbedtls_test_unhexify():
- Align naming of variables related to the expected okm
- Rename `okm_hex[]` to `okm_string[]`
- Added TEST_ASSERT( expected_okm_len <= sizeof( okm ) ) to check
that the okm[] buffer is large enough for the okm output.

Command to find the files in which lines have gone
larger than 79 characters due to the renaming:
grep '.\{80\}' \
`git diff-tree --no-commit-id --name-only -r HEAD` \
| grep hexify

`test_hkdf` in the hkdf test suites consumed stack of ~6KB with
6 buffers of ~1KB each. This causes stack overflow on some platforms
with smaller stack. The buffer sizes were reduced. By testing, the sizes
can be reduced even further, as the largest seen size is 82 bytes(for okm).
