cmd/dist: fix line numbers in goc2c generated files

Browse Source 
We have to reset the global lineno variable before
processing each file otherwise line numbers will be
offset by the number of lines in the previous file.

The following examples are from the beginning of the
ztime_linux_amd64.c file which is generated from
time.goc in the runtime package.

Before:
    #line 2483 "/home/apm/src/go/src/pkg/runtime/time.goc"
    static Timers timers;
    static void addtimer ( Timer* ) ;
    void
    time·Sleep(int64 ns)
    {
    #line 2492 "/home/apm/src/go/src/pkg/runtime/time.goc"

After:
    #line 16 "/home/apm/src/go/src/pkg/runtime/time.goc"
    static Timers timers;
    static void addtimer ( Timer* ) ;
    void
    time·Sleep(int64 ns)
    {
    #line 25 "/home/apm/src/go/src/pkg/runtime/time.goc"
