python3-adafruit-blinka: Disable on musl

it provides prebuilts which are linked against glibc. so disable it for
musl

Fixes
microcontroller/bcm283x/pulseio/libgpiod_pulsein contained in package python3-adafruit-blinka requires libc.so.6(GLIBC_2.4), but no providers found in RDEPENDS:python3-adafruit-blinka? [file-rdeps]
