Fix dependencies so show-build-deps won't fail

[tornaria]

Split up from #47888 to avoid long CI in that PR.

This fixes dependencies in four packages and also fixes handling of *-32bit deps.

Before this change:

$ for p in bcachefs-tools brother-dcp197c-lpr gcc-multilib nvidia nvidia470 python3-QtPy python3-google-api-python-client qgis ; do ./xbps-src show-build-deps -K $p > /dev/null; done
=> ERROR: bcachefs-tools-1.3.6_1: dependency 'libudev-devel' does not exist!
=> ERROR: brother-dcp197c-lpr-1.1.3_6: dependency 'glibc-32bit' does not exist!
=> ERROR: gcc-multilib-12.2.0_2: dependency 'glibc-32bit' does not exist!
=> ERROR: nvidia-535.146.02_1: dependency 'glibc-32bit' does not exist!
=> ERROR: nvidia470-470.223.02_1: dependency 'glibc-32bit' does not exist!
=> ERROR: python3-QtPy-2.4.1_1: dependency 'font-liberation-ttf' does not exist!
=> ERROR: python3-google-api-python-client-2.80.0_2: dependency 'python3-Django' does not exist!
=> ERROR: qgis-3.34.1_1: dependency 'opencl-clhpp' does not exist!

After this change, there is no error. Also running common/scripts/xbps-cycles.py will do every package (Those 8 are all the failures I got).

Note that the errors for python3-QtPy and python3-google-api-python-client show only if #47888 is applied, since they are for checkdepends.
