The strcpy() function is deprecated across the kernel tree and
moving towards complete elimination. It provides no verification
limits against buffer overflows and does not guarantee strict boundary
restrictions [1][2].

Replace instances of strcpy() in `net/bluetooth/bnep/core.c` with the safer
strscpy() alternative. Since both target destination blocks are
statically allocated fixed-size arrays within their structure definitions,
leverage the compile time sizeof() operator to explicitly pass the
destination buffer capacities.
