Fixed invocation of shootout/reverse-complement.

Input generation with the shake-based nofib-run didn't work for
shootout/reverse-complement, so the test was never run.
Created a boot.sh script analogous to shootout/k-nucleotide.
Compilation of fasta-c.c and revcomp-c.c gave warnings for
ignored return values of 'write' - suppressed them by explicitly
ignoring with '(void)!' (negation and void cast).
