[PATCH] kbuild: kallsysms: throw away result of fgets()

[Ben Dooks <ben-linux@fluff.org>]

fgets() is being used to skip a line, so throw the result away
to remove the following warning:

scripts/kallsyms.c: In function ‘read_symbol’:
scripts/kallsyms.c:112: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result
