alpha: Use generic gettimeofday implementation

  It makes alpha no longer reports information about a system-wide
time zone and moves the version logic on the alpha implementation.

Checked on a build and check-abi for alpha-linux-gnu.

This appears to have lost the gettimeofday symbol from static libc - I see 
an undefined reference linking nptl/tst-cond8-static.
