Robert Griesemer 9956a5423e text/scanner: guard against installed IsIdentRune that accepts EOF
IsIdentRune may be installed by a client of the scanner. If the
installed function accepts EOF as a valid identifier rune, Scan
calls may not terminate.

Check for EOF when a user-defined IsIdentRune is used.

Fixes #50909.
