zoom-us: update 2.0.106600.0904 -> 2.0.123200.0405, cleanup

Apart from version update:
- remove some packages from `LD_LIBRARY_PATH`. I haven't found any
references for them. Most of them were copypasted from AUR expression
- found an implicit reference to `pidof`, in my case this caused warnings
about mismatched Glibc version. I've found implicit reference to `sh` too,
with Glibc warning too, but I don't know how to fix this, and looks like it's
only a warning
