rpm.spec.in: Fix doc packaging issues w/ RHEL 7+ On RHEL 7 and later (not sure exactly whether this is a product of the newer RPM release or something distro-specific), macros are lazily expanded, so we need to set _docdir using %global (which expands at definition time) and prior to _prefix and _datarootdir (which affect _defaultdocdir.) Otherwise, _docdir is set to a subdirectory of /opt/libjpeg-turbo/share/doc or /opt/libjpeg-turbo/doc. The former (which happens on RHEL 7) leads to incorrect documentation packaging (the docs should be packaged under /usr/share/doc per Red Hat standards), and the latter (which happens on RHEL 8) leads to an RPM build error.
