Lidong Chen b970a5ed96 gettext: Integer overflow leads to heap OOB write ...

The size calculation of the translation buffer in
grub_gettext_getstr_from_position() may overflow
to 0 leading to heap OOB write. This patch fixes
the issue by using grub_add() and checking for
an overflow.

Fixes: CVE-2024-45777
