timer/linux: rename component-specific functions

Several component-specific functions were named with a prefix of
"opal_timer_base", which was quite confusing.  Rename them to have a
prefix "opal_timer_linux" to make it clear that they are here in this
component (and different than *actual* opal_timer_base symbols).
