Make qmake to pass all UTF-8 characters unchanged through parser.

QMakeProject::parse() calls QString::simplified(), which assumes any
byte 0xA0 in multibyte UTF-8 characters is a space character (0x00A0 is
unicode character NBSP [non-breaking space]) and replaces those bytes
with regular space, corrupting the UTF-8 string.

Fixed by temporarily changing all 0xA0 bytes in parser input to another
non-space character 0x01A0. This is safe replacement as qmake doesn't
accept unicode .pro files, so there should never be actual NBSP or the
replacement 0x01A0 characters in a valid .pro file.

Note that there are a couple of more uses of QString::simplified() in
qmake, but those do not deal with strings that need to be UTF-8
compatible as far as I can tell, so no need to touch them.
