perf tools: Fix build with bison 2.3 and older.

commit 85df3b3769222894e9692b383c7af124b7721086 upstream.

The %name-prefix "prefix" syntax is not available on bison 2.3 and
older. Substitute with the -p "prefix" command-line option for
compatibility with older versions of bison.

This patch fixes this build error with older versions of bison.
