lib: libc: Kconfig: Correct dependencies for MINIMAL_LIBC_SUPPORTED

The MINIMAL_LIBC_SUPPORTED option is supposed to indicate that the
minimal C library implementation can be chosen and many tests use
this option as a filter for scenarios where the MINIMAL_LIBC option
is enabled.

On the other hand, the REQUIRES_FULL_LIBC option tells that the minimal
C library is insufficient and it prevents the MINIMAL_LIBC option from
being enabled. But it should also cause that MINIMAL_LIBC_SUPPORTED is
no longer enabled, otherwise for targets requiring a complete C library
implementation, tests using the filtering mentioned above will not be
actually performed with the minimal C library.

This commit removes the above discrepancy by moving the dependency on
!REQUIRES_FULL_LIBC from MINIMAL_LIBC to MINIMAL_LIBC_SUPPORTED.
