perf symbols: Fix builds with NO_LIBELF set
Build currently fails:
$ make -C tools/perf O=/tmp/pbuild NO_LIBELF=1
util/symbol.c: In function ‘dso__load’:
util/symbol.c:1128:27: error: ‘struct symsrc’ has no member named ‘dynsym’
CC /tmp/pbuild/util/pager.o
make: *** [/tmp/pbuild/util/symbol.o] Error 1
make: *** Waiting for unfinished jobs....
Moving the dynsym reference to symbol-elf.c reveals that NO_LIBELF requires
NO_LIBUNWIND:
$ make -C tools/perf O=/tmp/pbuild NO_LIBELF=1

This patch fixes both.
