dex2oat: Avoid an open from /proc/self/fd
ReadCommentedInputStream reads a text file by line, filters out empty or
commented line, then send the line to a callback. The original
implementation uses ifstream and std::getline.
aosp/1734115 added a way to read the text file by FD. Since there
doesn't seem to be a way in C++ to convert the FD to an input stream,
it creates one by opening /proc/self/fd/43.
In the context of Comp OS, this requires giving dex2oat a special open
privilege to "authfs".
This change replaces ifstream/std::getline with f(d)open/getline(3).
