tests/senml: do no include saul_default

[fjmolinas]

Contribution description

Seems like my last test of #16384 was too old since an error sneaked in, the saul tests expect there to be no saul device present... so do not include saul-default.

Testing procedure

EXTERNAL_BOARD_DIRS= RYOT_CI=1 BOARD=samr21-xpro make -C tests/senml_saul/ flash test -j
Building application "tests_senml_saul" for "samr21-xpro" with MCU "samd21".
