pjproject: Configurable setting for cnonce to include hyphens or not

NEC SIP Station interface with authenticated registration only supports cnonce
up to 32 characters.  In Linux, PJSIP would generate 36 character cnonce
which included hyphens.  Teluu developed this patch adding a compile time
setting to default to not include the hyphens.  They felt it best to still
generate the UUID and strip the hyphens.
They have indicated it will be part of PJSIP 2.10.
