* gguf : align the data section relative to the GGUF start, not the file

gguf_init_from_file_ptr reads a GGUF from the current file position, but padded
the data section from file offset 0, so a GGUF embedded at an offset that is not
a multiple of the alignment loaded without error and returned wrong tensor data.

Also adds llama_adapter_lora_init_from_file_ptr, and disables mmap with a warning
when an embedded data section is not aligned, instead of asserting in ggml.

* llama : load lora from path through the FILE* variant

The test now checks that mmap is disabled only for an unaligned offset.
