Fix AOSP_BUILD interpretting "9.0" as regex not fixed string

[simora]

The following line in build_template.go is interpretting "9.0" as regex not a fixed string. I've included all the necessary commands to prove and reproduce and a pull request to fix.

AOSP_BUILD=$(curl --fail -s ${AOSP_URL_BUILD} | grep -A1 "${DEVICE}" | egrep '[a-zA-Z]+ [0-9 {4})' | grep "${ANDROID_VERSION}" | tail -1 | cut -d"(" -f2 | cut -d"," -f1)

# AOSP_URL_BUILD="https://developers.google.com/android/images"
# AOSP_URL_BRANCH="https://source.android.com/setup/start/build-numbers"
# ANDROID_VERSION="9.0"
# DEVICE=taimen
# curl --fail -s ${AOSP_URL_BUILD} | grep -A1 "${DEVICE}" | egrep '[a-zA-Z]+ [0-9]{4}\)' | grep -F "${ANDROID_VERSION}" | tail -1 | cut -d"(" -f2 | cut -d"," -f1
