perf symbols: Include elf.h header regardless LIBELF_SUPPORT

The elf.h header file is used for NO_LIBELF build too so it should be
included anyway.  Also remove duplicated include of the header file in
symbol-*.c.  This patch fixes following build error on NO_LIBELF build:

    CC tests/hists_link.o
tests/hists_link.c: In function ‘setup_fake_machine’:
tests/hists_link.c:132:8: error: ‘STB_GLOBAL’ undeclared (first use in this function)
tests/hists_link.c:132:8: note: each undeclared identifier is reported only once for each function it appears in
