partitions: android: test: remplace mkdir shell command

Without that fix, we have the following warning:
      CC       partitions/android.o
    ../../../../samsung-ipc/tests/partitions/android.c:
    In function ‘create_dummy_modem_image’:
    ../../../../samsung-ipc/tests/partitions/android.c:52:9: warning:
    ignoring return value of ‘system’ declared with attribute
    ‘warn_unused_result’ [-Wunused-result]
       52 | system("mkdir -p /tmp/libsamsung-ipc.55f4731d2e11e85bd889/");
          | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
