Remove trailing comma in configure.ac.

Summary:
- We were inadvertantly emitting a superfluous comma when generating the
configure script, causing it warn on execution. This was caused by
separating two AC_DEFINE() invocations w/ a comma.

Test Plan:
- fbconfig -r folly && fbmake runtests
- ./configure && make check on Ubuntu/FC/Mac
