qt: dependency: Strip tool versions from newlines

When finding the Qt compilation tools (moc, uic, rcc, lrelease), the
version strings contain a trailing newline character. This results in a
stray newline in the meson log:

Detecting Qt5 tools
Program /usr/lib64/qt5/bin/moc found: YES 5.14.2
 (/usr/lib64/qt5/bin/moc)
Program /usr/lib64/qt5/bin/uic found: YES 5.14.2
 (/usr/lib64/qt5/bin/uic)
Program /usr/lib64/qt5/bin/rcc found: YES 5.14.2
 (/usr/lib64/qt5/bin/rcc)
Program /usr/lib64/qt5/bin/lrelease found: YES 5.14.2
 (/usr/lib64/qt5/bin/lrelease)

Strip the version to avoid this, resulting in a cleaner log:

Detecting Qt5 tools
Program /usr/lib64/qt5/bin/moc found: YES 5.14.2 (/usr/lib64/qt5/bin/moc)
Program /usr/lib64/qt5/bin/uic found: YES 5.14.2 (/usr/lib64/qt5/bin/uic)
Program /usr/lib64/qt5/bin/rcc found: YES 5.14.2 (/usr/lib64/qt5/bin/rcc)
Program /usr/lib64/qt5/bin/lrelease found: YES 5.14.2 (/usr/lib64/qt5/bin/lrelease)
