nrf_security: Fix kconfig extension macro inconsistent configuration

Fix the kconfig_check_and_set_base_to_val_depends extension macro
creating an inconsistent configuration.
This macro sets the base name to, but not the kconfig name.
For example:
'kconfig_check_and_set_base_to_val_depends(MBEDTLS_EXAMPLE_ALG,
PSA_WANT_EXAMPLE_ALG)' can create this inconsistentency:
CONFIG_PSA_WANT_EXAMPLE_ALG: true
MBEDTLS_EXAMPLE_ALG: true
CONFIG_MBEDTLS_EXAMPLE_ALG: false

This means that the macro cannot be used to check a series of chained
dependencies.

Make sure that the macro modifies the value of both the base and the
kconfig variable.
