[PATCH 1/4] selftests: riscv: Add definition of BIT() macro

[Charlie Jenkins via B4 Relay <devnull+thecharlesjenkins.gmail.com@kernel.org>]

From: Charlie Jenkins <thecharlesjenkins@gmail.com>

The BIT() macros is used by the validate_v_ptrace() test case, but not
defined. Include linux/bits.h to pull in this definition. To ensure that
the header in the kernel source is used, add tools/include to the header
search path.

Fixes: 30eb191c895b ("selftests: riscv: verify ptrace rejects invalid vector csr inputs")
