ridiculousfish e74b9d53df Do not use posix_spawn on glibc < 2.24 
This concerns the behavior of posix_spawn for shebangless scripts. At some
point, glibc started executing them using `sh`, which is desirable for
fish's shebangless support (see #7802). On glibcs without that behavior
the shebangless test fails. So this change disables posix_spawn on older
glibcs.

It's not easy to figure out when that happened but it definitely happens
in glibc 2.28, and does not happen in glibc 2.17. Presumably the new
behavior is present in glibc 2.24 (see BZ#23264) so that's the cutoff:
posix_spawn is no longer allowed on glibc < 2.24.

This fixes the noshebang test failures on Ubuntu Xenial and Centos 7.
See discussion at bottom of #8021.
