Aaron Plattner 7ab1832fe1 objtool: Remove max symbol name length limitation ...

[ Upstream commit f404a58dcf ]

If one of the symbols processed by read_symbols() happens to have a
.cold variant with a name longer than objtool's MAX_NAME_LEN limit, the
build fails.

Avoid this problem by just using strndup() to copy the parent function's
name, rather than strncpy()ing it onto the stack.
