bpf: accept # as an inline comment char

This little patch makes the BPF assembler accept '#' as an inline
comment character, which clang -S seems to use.

gas/
	* config/tc-bpf.c (comment_chars): Add '#'.
	* doc/c-bpf.texi (BPF Special Characters): Add note that '#' may
	be used for inline comments.
