Hengqi Chen 1d375d6546 selftests/bpf: Enable cpu v4 tests for LoongArch 
Enable the cpu v4 tests for LoongArch. Currently, we don't have BPF
trampoline in LoongArch JIT, so the fentry test `test_ptr_struct_arg`
still failed, will followup.

Test result attached below:

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
