[flang-commits] [flang] [flang] include sys/wait.h for EXECUTE_COMMAND_LINE (PR #77675)

[Dan McGregor via flang-commits]

https://github.com/dankm created https://github.com/llvm/llvm-project/pull/77675

Linux defines WEXITSTATUS in stdlib.h, but at least FreeBSD and NetBSD only define it in sys/wait.h. Include this header unconditionally, since it is required on the BSDs and should be harmless on other platforms.

Fixes FreeBSD build after #74077.
