  [gcov] Don't skip leading zeros when reading a string

Even a 2003 version of gcov_read_string does not have the behavior
described by rL204881. The wrong impression might come from
libclang_rt.profile (GCDAProfiling.c)'s corrupted output (since the
initial import rL144865). Note, the corrupted output crashes gcov.
