qtbase: Fix build with musl

This is a generic fix to accomodate musl which is adhering to posix
and doesnt have legacy to carry, so lets invert the conditional so the
special legacy case of glibc is checked and else part then covers rest
of cases which are newer glibc/uclibc and musl

+Subject: [PATCH] linux-oe-g++: Invert conditional for defining QT_SOCKLEN_T
+
+This helps to make sure that QT_SOCKLEN_T is defined to be 'int'
+only when its glibc < 2 and not also for the libraries which may define
+it as per standards but are not glibc, e.g. musl
