package/eudev: Fix monitor starting for kernels w/o CONFIG_SHMEM

Browse Source 
When the kernel has CONFIG_SHMEM disabled, /dev is a ramfs (instead of a
tmpfs) and the name_to_handle_at system call is not supported. This
causes eudev's monitor application to exit on startup.

Upstream eudev has added this fix which is not yet part of a release.

Subject: [PATCH] src/libudev/libudev-monitor.c: do not check if /dev is tmpfs
This check fails for buildroot systems where /dev is not mounted
as a tmpfs filesystem. Dropping this check should be safe even
on regular systems.
This solves issue #172.
