tracing/syscalls: select kallsysms

Syscall tracing must select kallsysms.

The arch code builds a table to find the syscall metadata by syscall
number. It needs the syscalls names resolution from the symbol table
to know which name found on the syscalls metadatas match a function
pointer from the arch sys_call_table.
