package/pthreadpool: fix thread dependency

Browse Source 
On autobuilder config with BR2_TOOLCHAIN_HAS_THREADS not set the
following error happens when building the pthreadpool package:

```
-- Looking for pthread_create in pthreads
-- Looking for pthread_create in pthreads - not found
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - not found
-- Check if compiler accepts -pthread
-- Check if compiler accepts -pthread - no
CMake Error at /home/buildroot/instance-0/output-1/host/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
  Could NOT find Threads (missing: Threads_FOUND)
Call Stack (most recent call first):

  CMakeLists.txt:143 (FIND_PACKAGE)

-- Configuring incomplete, errors occurred!
```

This can be reproduced with:

```
cat >.config <<EOF
BR2_armeb=y
BR2_TOOLCHAIN_BUILDROOT_UCLIBC=y
BR2_PTHREADS_NONE=y
BR2_PACKAGE_PTHREADPOOL=y
EOF
make olddefconfig
make pthreadpool
```

Since the introduction of this package in [1], the dependency was not
included. Since this package was part of the tensorflow-lite
dependencies that required thread it was not an issue.

This patch adds BR2_TOOLCHAIN_HAS_THREADS in the dependency to avoid
errors when built as a standalone package.
