[PATCH oclock] Add xt to PKG_CHECK_MODULES

[Robert Hooker]

From: Robert Hooker <robert.hooker at canonical.com>

Fixes this build failure with ld --no-add-needed

  CCLD   oclock
/usr/bin/ld: oclock.o: undefined reference to symbol 'XtAddEventHandler'
/usr/bin/ld: note: 'XtAddEventHandler' is defined in DSO /usr/lib/libXt.so.6 so try adding it to the linker command line
/usr/lib/libXt.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
