Revert "[PATCH] binfmt_elf: randomize PIE binaries (2nd try)"

This reverts commit 59287c0913cc9a6c75712a775f6c1c1ef418ef3b.

Hugh Dickins reports that it causes random failures on x86 with SuSE
10.2, and points out

  "Isn't that randomization, anywhere from 0x10000 to ELF_ET_DYN_BASE,
   sure to place the ET_DYN from time to time just where the comment
   says it's trying to avoid? I assume that somehow results in the error
   reported."

(where the comment in question is the existing comment in the source
code about mmap/brk clashes).
