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).

Tested with GCC on Linux (have nothing else). I also adapted the Makefile to use the script (as k-nucleotide does). I ran make boot and make in the folder, it generates the correct files, but I couldn't test the actual invocation with the make based system.

Edit: fixes #26 (closed)
