Rename Fortran requirement to fix option generation

So, `depends_on :fortran => :optional` will generate "--with-fortran"
rather than "--with-fortranRequired".
fftw: use optional dep for fortran
libgetdata: use optional dep for fortran
libgetdata: style
R: use optional dep for valgrind
gearman: use optional dep for mysql
soci: use optional dep for boost
