fix(build.sh): Cosmetic spacing fix (#199)

* fix(build.sh): Cosmetic spacing fix

Iterm has an issue with rendering multi byte unicode chars. This
commit adds an extra space to certain emojis on iterm only.

This fixes current rendering issues on Linux term because that extra
space was added previously unconditionally.

* fix(build.sh): Avoid uninitialized variable ITERM_PROFILE
