Switch git_mmap to use pread.
Now that Git depends on pread in index-pack its safe to say we can
also depend on it within the git_mmap emulation we activate when
NO_MMAP is set. On most systems pread should be slightly faster
than an lseek/read/lseek sequence as its one system call vs. three
system calls.
We also now honor EAGAIN and EINTR error codes from pread and
restart the prior read.
