test/hil: fix esp32 audio_test_freertos (FreeRTOS tick), skip metro_m4
Enabling the audio test fleet-wide surfaced failures on esp32-p4/s3 and
metro_m4_express: the UAC mic enumerates but arecord fails the iso IN read
with EIO, while 18 other boards pass strict=1.000.
esp32: root cause is the FreeRTOS tick rate. ESP-IDF defaults
CONFIG_FREERTOS_HZ to 100, so the audio task wakes only every 10 ms and
can't service the 1 ms UAC iso frames -> underrun -> arecord EIO. (The same
dwc2 driver passes on STM32, whose FreeRTOSConfig is 1000 Hz.) Set
CONFIG_FREERTOS_HZ=1000 in the example sdkconfig.defaults; the example
defaults are honored in the generated sdkconfig alongside the BSP's, so this
takes effect.
metro_m4_express (samd51): not tick-rate -- its FreeRTOSConfig is already
1000 Hz like the passing boards -- so it's a separate iso-IN issue, skipped
for now.
