Copy shim and grub efi binaries to tftp root

Currently uefi_pxe_bootfile_name defaults to bootx86.efi, but puppet
doesn't copy any file to this location. This change copies the signed
grub shim efi to tftp root bootx86.efi, and also the signed grub
binary to grubx64.efi.

This means UEFI boot with PXE will now work by default by doing a grub
network boot instead of using iPXE. And since all EFI binaries are
signed, it should even be possible to enable Secure Boot for the whole
baremetal provisioning process.

The pxe parameter `uefi_pxe_bootfile_name` is now managed by puppet, keeping
the ironic default of `bootx64.efi`.
The shim EFI binary is copied to the TFTP root directory, to a file named
the value of `uefi_pxe_bootfile_name`. The grub EFI binary is copied to
the TFTP root directory to a file named `grubx64.efi`.
With these changes, using the pxe boot driver with UEFI boot will result in
a grub network boot which is Secure Boot capable.
