community/firmware-bq-picmt: squash firmware blobs (MR 2619)

Strictly speaking firmware-bq-picmt is not needed anymore because
the msm-firmware-loader can be used to load the picmt firmware from
the firmware partitions. However, this package contains quite recent,
largely unmodified firmware from Qualcomm so it still seems useful
to keep if someone wants to test more recent firmware on some other
device (provided that their device does not verify firmware signatures).

To make this firmware package consistent with firmware-qcom-db410c,
squash the firmware blobs using pil-squasher so only one file needs
to be loaded rather than many small ones.
