Subject: [PATCH] app/prj.conf: disable PICOLIBC with CONFIG_MINIMAL_LIBC=y

Starting from Zephyr commit f0daf904bb02, CONFIG_PICOLIBC is on by
default.

PICOLIBC does not seem compatible with sparse yet:
https://github.com/zephyrproject-rtos/zephyr/issues/63003

Even if it were compatible with sparse, it seems like a pretty big
change that we should not immediately and blindly accept.
