ProcessPipe.pm: Use read not sysread

While playing with git fast export I discovered that mixing <> and
read would give inconsistent results.  I tracked the issue down to
using sysread in ProcessPipe instead of plain read.

If it is desirable to use readline I can't see how using sysread
can work as readline to be efficient needs to use buffered I/O.
