[aur-general] mksrcinfo bug: PKGBUILD stdout appears in mksrcinfo

mksrcinfo will include anything the PKGBUILD writes to stdout in the body
of the PKGBUILD (i.e. not in any prepare/build/package/etc. functions when
being sourced, for example:

echo "Hello world."
prepare() {}
build() {}
package() {}

... which will generate an .SRCINFO file with "Hello world." as the first
line.  This .SRCINFO file is then not parseable by AUR4 when trying to push
it to the package's git repository, which will end up with an error that
looks like this:

$ git push -u origin master:master

remote: error: hook declined to update refs/heads/master

The fix should prevent the PKGBUILD's stdout output from appearing in the
.SRCINFO that mksrcinfo generates.
