tests/pkg_edhoc_c: blacklist esp32-wroom-32

According to ieee802154_radio_confirm_transmit docs, the parameter of
confirm_op for IEEE802154_HAL_OP_TRANSMIT is to be populated as an out
parameter -- but this implementation unconditionally left info
unpopulated. Thus, when run with LLVM, _fsm_state_tx_process_tx_done
looked into an uninitialized info and thus crashed into failing
assertions.

Closes: RIOT-OS#17591

The shared `build-libs` directory needs to be available for
modules/packages that depend on the SDK before that package
is eventually compiled.

Packages are downloaded, patched and prepared before any
module is compiled. By adding the directory creation and
header as a dependency of `PKG_PREPARE` we make sure the
rule is run before compilation starts.

This also includes header files such as `esp32_idf_version.h`.

Using EXTERNAL_MODULE_PATHS works fine when only using Kconfig for
configuratio, but when using it for dependencies this value is not
set since it depends on Kconfig. Instead use EXTERNAL_MODULE_DIRS
and filter matching on Kconfig files.

This extends the error messages to check if a symbol could not be set
due to its visibility.

As the `dir` make function considers the last slash as part of the
directory-part of a file name, we don't need to add an extra one.
