The input to the jarsigner (specifically the password, alias,
file name, etc.) can contain spaces, so the arguments need
to be quoted.

make the MinGW build of lupdate work for non-admin users

Windows User Access Control thinks that lupdate is an installer,
because of the string "update" in the executable name.
MSVC automatically creates and embeds a manifest into the executable
to state that lupdate doesn't need admin rights.
For MinGW we now embed a handcrafted manifest.

[ChangeLog][lupdate] Fixed lupdate requiring admin rights when built
with MinGW.
