Subject: Create usymname and usymdata variant that trigger
 STP_NEED_VMA_TRACKER.

* tapset/context-symbols.stp (syname, symdata): Pass NULL for kernel address.
* tapset/ucontext-symbols.stp: New file defining usymname and usymdata.
* testsuite/systemtap.context/usymbols.exp: Use usymname, remove
  STP_NEED_VMA_TRACKER hack.
* testsuite/buildok/usymdata.stp: New test.
* testsuite/buildok/usymname.stp: Likewise.
