    Add quoting to literal curly brackets
    
    These curly brackets are already treated as literals by the shell, so
    let's make that explicit for clarity, and silence a ShellCheck warning
    at the same time.

Subject: [PATCH 2/7] Always free the arg list passed to rpmGlob()

Even though the actual implementation of rpmGlob() does not allocate the
passed arg list (av) if the return code (rc) is non-zero or arg count
(ac) is 0, it's the responsibility of the caller (rpmInstall() here) to
free that memory, so make sure we do that irrespectively of the above
conditions.

Subject: [PATCH 3/7] Fix resource leak in Fts_children()

This function is not used anywhere within our codebase (and neither is
it part of the public API) so it's basically a no-op... Still, rather
than yanking it completely, let's just silence the Coverity error here.

Subject: [PATCH 4/7] Fix memory leak in fts_build()

Turns out this leak is already fixed in glibc's current version of fts.c
(where our copy originates from), so let's just backport that.

Subject: [PATCH 6/7] Fix memory leak with multiple %lang-s in one line

We permit two equivalent forms of specifying a list of languages per
file:

  %lang(xx,yy,zz) /path/to/file
  %lang(xx) %lang(yy) %lang(zz) /path/to/file

The leak was when parsing the second form.
