e4defrag: fix ppc build

From: Kyle McMartin <[email protected]>

ppc glibc seems to be missing sync_file_range, so we fell back to the local define, and there ppc differs as well, so the build was failing.

Thanks to Kyle for the patch w/ the tidy solution.

e4defrag can be found in the 'master', 'next', and 'pu' branches of the e2fsprogs repository. It's not in the 'maint' branch, so it's not in any of the e2fsprogs 1.41.x releases. The 'master' branch contains the in-development work that will be showing up in e2fsprogs 1.42; so far the big things that there is the on-going merge 64-bit block number support, and e4defrag.
