Incorrect manifest verification failures for adopt_11.0.5_10_mac/x64_hotspot

[cwbriones]

.jdkw

JDKW_RELEASE=latest
JDKW_DIST=adopt
JDKW_BUILD=10
JDKW_VERSION=11.0.5
JVM_IMPL=hotspot

This results in jdkw_id=adopt_11.0.5_10_mac/x64_hotspot.

On a run with a pre-existing download, manifest verification attempts to dump the computed checksum at a temp directory using the above ID, e.g. /var/folders/j2/v5s4xyw521b8ktyvhl131vx80000gn/T//adopt_11.0.5_10_mac/x64_hotspot-37105.94605677 (ref)

Because of the extra '/' this results in a "No such file or directory" and manifest verification fails. This doesn't occur with other distributions because the id does not contain the slash (e.g. zulu_8.0.212_8.38.0.13_macosx_x64).
