Don't run plugins on src.rpm unpacking (RhBug:2316785)
Browse files Browse the repository at this point in the history 
Source packages aren't really "installed", just unpacked, and plugins
operate on real transactions by design, so disable all hooks for those.

This fixes, in particular, src.rpm installations done by a regular user
(a fairly common case) on systems equipped with a plugin that needs root
privileges (e.g. the ima plugin), which would otherwise cause a spurious
warning or even failure (see RhBug:2316785).

Do this by setting RPMTRANS_FLAG_NOPLUGINS for the duration of source
unpacking.  This ensures that ts->plugins, if not populated yet, will
remain empty during rpmInstallSource() (rpmtsSetupTransactionPlugins()
bails out if the flag is present).

However, if any binary packages are among the rpmInstall() arguments,
ts->plugins will have been populated by the time rpmInstallSource() is
called, so we also need to check for the flag in the hooks themselves,
too, and prevent them from running if it's present.

Reuse the plugin development test, we don't have anything better at the
moment and it does the job well.
