bpf: Fixed register parsing disambiguating with possible symbol.
This changes parse_bpf_register to detect possible symbols that start with valid
register name, however due some following characters are not.
Also changed the regs-for-symbols-pseudo.s, adding some entries that
should not error if parser is properly detecting the symbol.
