Eliminate compiler warnings

Many programs use nested functions, which now result in a linker
warning about executable stack.  Hide this warning.  Also, rewrite a
loop in the plymouth plugin to avoid warning about signed overflow.
This change also makes the plugin pick the alphabetically first
process entry instead of the last, in case many plymouth processes are
found (which should be unlikely).

* Makefile (plugin-runner, dracut-module/password-agent,
  plugins.d/password-prompt, plugins.d/mandos-client,
  plugins.d/plymouth): New target; set LDFLAGS to add "-Xlinker
  --no-warn-execstack".
* plugins.d/plymouth.c (get_pid): When no pid files are found, and we
  are looking through the process list, go though it from the start
  instead of from the end, i.e. in normal alphabetical order and not
  in reverse order.
