vim-patch:9.0.0803: readblob() cannot read from character device
Problem: readblob() cannot read from character device.
Solution: Use S_ISCHR() to not check the size. (Ken Takata, closes vim/vim#11407)
https://github.com/vim/vim/commit/43625762a9751cc6e6e4d8f54fbc8b82d98fb20d
S_ISCHR is always defined in Nvim.
