perf symbol-elf: Decode dynsym even if symtab exists
In Fedora34, libc-2.33.so has both .dynsym and .symtab sections and
most of (not all) symbols moved to .dynsym. In this case, perf only
decode the symbols in .symtab, and perf probe can not list up the
functions in the library.
To fix this issue, decode both .symtab and .dynsym sections.
Without this fix,

$ ./perf probe -x /usr/lib64/libc-2.33.so -F
