lib/jpeg: avoid calling malloc and free

Since commit 1d029b40c9de ("lib/jpeg: Replace decoder with Wuffs'
implementation"), a relatively large heap allocation is needed to decode
many JPEGs for use as work area. The prior decoder did not need this,
but also had many limitations in the JPEGs it could decode, was not as
memory-safe and quickly crashed under fuzzing.

This commit keeps using Wuffs' JPEG decoder, but it no longer requires
any heap allocation (and thus configuring the heap size depending on how
big a bootsplash image you want to support).
