libfuse: allow disabling adaptive readdirplus
This switches the -o no_readdirplus option to a tristate
string: -o readdirplus=(yes|no|auto)
Telling the kernel to always use readdirplus is beneficial to
filesystems (e.g. GlusterFS) where the cost to perform readdir
and readdirplus are identical.
The default remains "auto" (if supported).
