strbuf_getwholeline: use getc macro
strbuf_getwholeline calls fgetc in a tight loop. Using the getc form, which can be implemented as a macro, should be faster (and we do not care about it evaluating our argument twice, as we just have a plain variable). On my glibc system, running "git rev-parse refs/heads/does-not-exist" on a file with an extremely large (1.6GB) packed-refs file went from (best of 3 runs): real 0m19.383s user 0m18.876s sys 0m0.528s to: real 0m18.900s user 0m18.472s sys 0m0.448s for a wall-clock speedup of 2.5%.
