build: fix meson build in CI environments

This is to fix a build error with meson in GNU/Linux that is caused
by using the 'more' command to read the VERSION file. The error:

    config/meson.build:10:10: ERROR:  String
    '::::::::::::::\n<RTE_SDK_PATH>VERSION\n::::::::::::::\n19' cannot be
    converted to int

The command 'more' prints the file name before the actual
contents of the file when it's being run without a controlling terminal.
This could happen in CI environments.

Please refer to:

Fixes: c04172b5f031 ("build: add single source of DPDK version number")
Fixes: d320fe56bd51 ("build: use version number from config file")
