 jq: fix build with Xcode 12

 The jq configure system checks whether `lgamma_r()` is defined in
 libm, but not whether it is actually declared. On macOS, that is not
 the case unless `_REENTRANT` was defined prior to including `math.h`.
 Xcode 12 changed the defaults, so that using an undefined symbol gives
 a hard error, breaking the build.

 I had only run into this when building on an unreleased OS, but the
 error is actually specific to Xcode 12. This adjusts the builtin patch
 to address root cause, rather than just bypassing it, and applies the
 patch universally.
