Client: Fix plymouth agent; broken since 1.7.2.

Fix an very old memory bug in the plymouth agent (which has been
present since its apperance in version 1.2), but which was only
recently detected at run time due to the new -fsanitize=address
compile- time flag, which has been used since version 1.7.2.  This
detection of a memory access violation causes the program to abort,
making the Plymouth graphical boot system unable to accept interactive
input of passwords when using the Mandos client.

* plugins.d/plymouth.c (exec_and_wait): Fix memory allocation bug when
  allocating new_argv.  Also tolerate a zero-length argv.
