[PATCH v3 3/3] Ensured t5319 follows arith expansion guideline

["Son Luong Ngoc via GitGitGadget" <gitgitgadget@gmail.com>]

From: Son Luong Ngoc <sluongng@gmail.com>

As the old versions of dash is deprecated, dollar-sign inside
artihmetic expansion is no longer needed.
This ensures t5319 follows the coding guideline updated
in 'jk/arith-expansion-coding-guidelines' 6d4bf5813cd2c1a3b93fd4f0b231733f82133cce.
