The simpletrace compatibility code for systemtap creates a
function and some global variables for mapping to event ID
numbers. We generate multiple -simpletrace.stp files though,
one per target and systemtap considers functions & variables
to be globally scoped, not per file. So if trying to use the
simpletrace compat probes, systemtap will complain:
# stap -e 'probe qemu.system.arm.simpletrace.visit_type_str { print( "hello")}'
semantic error: conflicting global variables: identifier 'event_name_to_id_map' at /usr/share/systemtap/tapset/qemu-aarch64-simpletrace.stp:3:8

We already have a string used to prefix probe names, so just
replace '.' with '_' to get a function / variable name prefix
