[LTP] [PATCH 1/2] configure.ac: Require 2.64

[Li Wang]

Hi Petr,

I see other places also used 2.61, do you think we need to correct them as
well?
(e.g. open-posix and realtime)

$ git grep AC_PREREQ
configure.ac:AC_PREREQ(2.61)
testcases/open_posix_testsuite/configure.ac:AC_PREREQ(2.61)
testcases/realtime/configure.ac:AC_PREREQ(2.61)
