Find all files in packages

[Neradoc]

When circup looks at the board libraries it reads them all to find the version number and incompatible or invalid MPY files.
But it only looked at the first level files. This PR makes it look at all levels using the **/ pattern and recursive glob option.

At least one library, adafruit_displayio_layout has no file at the first level that contain version information (only an empty init).

before

❯ circup freeze
Found device at /Volumes/CIRCUITPY, running CircuitPython 8.0.0-beta.6-62-g7522522a0-dirty.
adafruit_displayio_layout==None

after

❯ circup freeze
Found device at /Volumes/CIRCUITPY, running CircuitPython 8.0.0-beta.6-62-g7522522a0-dirty.
adafruit_displayio_layout==1.19.10

Looks correct to me compared to the Glob library docs.
Not tested.
