[pacman-dev] [PATCH] libmakepkg/integrity: fix regression that broke --install

[Eli Schwartz]

In commit c6b04c04653ba9933fe978829148312e412a9ea7 package signing was
moved out of fakeroot, and as part of this process, the global pkgname
variable was modified in order to extract the built package names.

However, if a debug package was not available and added to the list of
packages, the function was aborted early, before the pkgname array was
restored, thereby corrupting the later stages of makepkg and
specifically the install_package function which needs to know which
pkgnames to install.

Fix this by inlining the debug package signing inside the `if` check,
and as added security switch to using `for pkg in "${pkgname[@]}"` as is
done in many other parts of makepkg, since package signing does not
depend on the value of pkgname for anything.
