makepkg: Only check regular files in $srcdir check

The 'grep -R' in the $srcdir check would not only grep regular files,
but also devices, symlinks (that might potentially point outside of
$pkgdir), pipes and so on. Use find to ensure only regular files are
examined.

This should fix https://bugs.archlinux.org/task/19975
