modpost: avoid using the alias attribute
Aiden Leong reported modpost fails to build on macOS since commit
16a473f60edc ("modpost: inform compilers that fatal() never returns"):
scripts/mod/modpost.c:93:21: error: aliases are not supported on darwin
Nathan's research indicates that Darwin seems to support weak aliases
at least [1]. Although the situation might be improved in future Clang
versions, we can achieve a similar outcome without relying on it.
This commit makes fatal() a macro of error() + exit(1) in modpost.h, as
compilers recognize that exit() never returns.
