    libio: Add terminating NUL when the first character is EOF in getdelim [BZ
#28038]

    POSIX requires that the buffer used by getdelim/getline add a
    terminating NUL whenever an EOF is read.

    * libio/iogetdelim.c (__getdelim): Add a NUL byte when the first
    __underflow is called.
    * libio/tst-getdelim.c (do_test): Add a test case for the bug.
