BZ #16418: Fix powerpc get_clockfreq raciness

This patch fix powerpc __get_clockfreq racy and cancel-safe issues by
dropping internal static cache and by using nocancel file operations.
The vDSO failure check is also removed, since kernel code does not
return an error (it cleans cr0.so bit on function return) and the static
code (to read value /proc) now uses non-cancellable calls.
