Spring-cleaning for rpmdeps

- Depgen helpers take nno args, their input comes from stdin. Eliminates
  popt vs ARGV_t mismatch which would've caused us to blow up if
  it weren't for a memleak on the generated argv.
- Another memleak on the file classifier in case rpmfcClassify()
  or rpmfcApply() fails - just free all allocated resources at exit.
- Remove fluff: fgets() is guaranteed to \0-terminate non-NULL returns,
  eliminate unused/useless variables
- Fixup indentation where busted
