Subject: bug#70714: realpath no error for unreadable-symlink

coreutils version: stable 9.5 (bottled)
OS version: macOS 13.6.6 (22G630)

`realpath` doesn’t behave correctly for unreadable symlinks:

wannes@Stefans-iMac ~ % ln -s . src        
wannes@Stefans-iMac ~ % grealpath -e src/..
/Users
wannes@Stefans-iMac ~ % chmod -h 000 src
wannes@Stefans-iMac ~ % grealpath -e src/..
/Users/wannes

Expected behaviour:

wannes@Stefans-iMac ~ % grealpath -e src/..
grealpath: src/..: Permission denied
