Fixed off-by-one error in uprobe_ssl.c where bpf_probe_read_user
was called with `data_len & (MAX_SSL_DATA - 1)` mask, causing
0-byte read when data_len was exactly 4096 (4096 & 4095 = 0).
This caused HTTP headers to be truncated when SSL_read returned
exactly 4096 bytes, resulting in host header values like "p"
instead of "platform".
The fix removes the incorrect bitwise operation and uses data_len
directly since it's already limited to MAX_SSL_DATA.
