The binary is looked on the system by the suffix of the packer class. This means binman was looking for btool_gzip on the system and not gzip.
Since a btool can have its btool_ prefix missing but its module and binary presence on the system appropriately found, there's no need to actually keep this prefix after listing all possible btools, so let's remove it.
This fixes gzip btool by letting Bintool.find_bintool_class handle the missing prefix and still return the correct class which is then init with gzip name instead of btool_gzip.
Additionally, there was an issue with the cached module global variable. The variable only stores the module and not the associated class name when calling find_bintool_class. This means that when caching the module on the first call to find_bintool_class, class_name would be set to Bintoolbtool_gzip but the module_name gzip only, adding the module in the gzip key in the module dictionary. When hitting the cache on next calls, the gzip key would be found, so its value (the module) is used. However the default class_name (Bintoolgzip) is used, failing the getattr call.
Instead, let's enforce the same class name: Bintool<packer>, whatever the filename it is contained in.
