selftests: net: Remove unnecessary backslashes in fq_band_pktlimit.sh

Address "grep: warning: stray \ before white space" warning from GNU
grep 3.12. This warns the misplaced backslashes before whitespaces
(e.g. \\' ' or '\ ') which leads to unspecified behavior [1].

We can just remove the backslashes before whitespaces as POSIX says:

  Enclosing characters in single-quotes ('') shall preserve the literal
  value of each character within the single-quotes.

and bourne-compatible shells behave so.
