[PATCH 2/7] scripts: modpost: increase buf_printf's buffer size

[Alexandre Courbot]

Rust tends to produce long symbol names; when trying to export symbols
from nova-core for nova-drm to link to, the 500 bytes of the internal
buffer used for symbol name formatting are not enough, making modpost
fail.

Fix this by increasing the size of the buffer used to format the symbols
to 1024 bytes. It is a stack buffer, but modpost is a user-space program
so that shouldn't be a problem.
