[PATCH] Fix grantpt basename namespace bug

[Aurelien Jarno]

Commit cf06a4e3 removed test-xfail-POSIX2008/unistd.h/linknamespace, but
left one basename namespace issue in grantpt. However this issue is not
visible with the default configuration buy only when configure is passed
the --enable-pt_chown option.
