xrick: Fix various errors/warnings

  * Piles of warnings in miniz when built with modern toolchain
  * Pointer arithematic error in PRNG
  * Casting between int and void * for file descriptors
  * Warning on non-color targets

Remaining:

  * Failure on XRGB888 LCDs due to issue with core LCD macros
  * Failure on interleaved greyscale LCDs (?)
  * HTML manual build failure
