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.
