Bug description:
  It looks like /run got mounted without noexec and the mtab write lies
  about it:

  $ grep -m1 /run /etc/mtab /proc/mounts 
  /etc/mtab:tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0
  /proc/mounts:tmpfs /run tmpfs rw,nosuid,relatime,size=1618980k,mode=755 0 0

  For completeness, /run should _actually_ be mounted noexec, even if
  it's root:root 0755.
