remove use of deprecated verbose option in build_step methods

[laraPPr]

We give a hard error on our systems when a warning is reported so we are already hitting this deprecation warning for EasyBuild 6.0.

ERROR: Installation of BLAT-3.7-GCC-12.3.0.eb failed: "DEPRECATED (since v6.0) functionality used: The 'verbose' parameter to build_step is deprecated and unneeded.; see https://docs.easybuild.io/deprecated-functionality/ for more information"
