build: use absolute path for M=

Use absolute path for M during checking kernelrelease. This will force
temporary objects be built in the current directory and not $kbuilddir
as it happened, e.g. in the current kernel scripts/Kbuild.include
try-run target (it is called with TMPOUT=M=. and during call
pwd=$kbuilddir). This should fix sandbox violation in Gentoo:
