#407 [PATCH] dcraw.cc: wrong variable type for find_green() return value

[pawelbsd]

Patch fixing build issue on FreeBSD 12.0-CURRENT:

dcraw.cc:9245:20: error: call to 'abs' is ambiguous
if (abs(i) < abs(c)) {

compiler:
FreeBSD clang version 3.8.0 (tags/RELEASE_380/final 262564) (based on LLVM 3.8.0)
Target: x86_64-unknown-freebsd12.0
Thread model: posix

find_green() returns float result, while i and c variables are unsigned type. Also abs() function
takes int argument. Attached patch uses proper type for for variables and fabsf() to
compare them.
