flac: change minimum and default of lpc_passes option to 1
...
Avoid use of uninitialized and uncomputed linear least square models
during ff_lpc_calc_coefs() for FF_LPC_TYPE_CHOLESKY. Fixes running
make fate-flac-16-lpc-cholesk with valgrind --undef-value-errors=yes.

flacenc: ensure the order is within the min/max range in LPC order search
...
This fixes use of uninitialized values when the FLAC encoder uses the
2-level, 4-level, and 8-level search methods. Fixes failure of the
fate-flac-24-comp-8 test when run using valgrind.
