Fix pointer sign conversion warnings in bcm2079x halimpl.
This fixes two warnings like:
system/nfc/halimpl/bcm2079x/gki/ulinux/gki_ulinux.c:895:12: warning:
returning 'int8_t *' (aka 'signed char *') from a function with result
type 'uint8_t *' (aka 'unsigned char *') converts between pointers to
integer types with different sign
All of the other similar-looking pieces of code return an `int8_t *`,
and gki_cb.com.OSTName[N] is an `int8_t *`. Given that it looks like
this is only used in one place (a debugging printf), changing the return
type doesn't seem problematic.
Bug: None
Test: mma. No more warning.
