Revert "PR9940: avoid duplicated calling of uprobes in shared libraries"
This fix caused a regression on fedora.
stap -ve 'probe process("/bin/ls").function("main") { log(pp()); }
probe process("/lib64/libc.so.6").function("*") { log(pp()); }' \
-c /bin/ls
hung (with stapio & ls processes spinning) upon startup.
