build: remove fdelt_chk backwards compatibility code
Now that we require glibc 2.17 or later, we no longer need to check for different return types in fdelt_chk. It was changed from unsigned long int to long int in glibc 2.16 . See this commit: https://sourceware.org/git/?p=glibc.git;a=commit;h=ceb9e56b3d1f8c1922e0526c2e841373843460e2 and related issue: https://sourceware.org/bugzilla/show_bug.cgi?id=14210.
