perf trace: Obtain errno strings by using arch_syscalls__strerrno()

Replace the errno_to_name() from the audit-libs with the newly
introduced arch_syscalls__strerrno() function.

With this change:

1.  With replacing errno_to_name() from audit-libs, perf trace
    does no longer require audit-lib interfaces.

2. In addition to 1, the audit-libs dependency can be removed
   for architectures that support syscall tables in perf.
   This is achieved in a follow-up commit.

3. With the architecture specific errno number/name mapping,
   perf trace reports can work across architectures.
