perf tools: Make find_vdso_map() more modular
In preparation for checking that the vectors page on the ARM architecture, refactor the find_vdso_map() function to accept finding an arbitrary string and create a dedicated helper function for that under util/find-map.c and update the filename to find-map.c and all references to it: perf-read-vdso.c and util/vdso.c.
