This PR fix two problems:

1. Error specification check error

When PADDLE_ENFORCE contains array index [], the grep -vx "$VALID_PADDLE_CHECK" will treat it as a regular expression metacharacter, resulting in a judgment error.

So this PR add -F to fix this problem.

  -F, --fixed-strings       PATTERN is a set of newline-separated strings

error example: https://github.com/PaddlePaddle/Paddle/pull/20972

2. PADDLE_ENFORCE using check match non-code content

Replace with a more precise regular expression
