Android: remove extra slash in script

No change to product, only to a developer script.

ANDROID_SDK_ROOT had a trailing slash, yet the script appended subpaths
with a slash prefix (ex. "/tools/"). This produced paths with
double-slashes.

This fixes the issue by deleting the trailing slash on the variable.

Bug: None
Test: source build/android/envsetup.sh && echo "$PATH"
